As an inerface beween he physical bus layer and he CAN proocol conroller, he TLE7250V drives he signals o he bus and proecs he microconroller agains inerferences generaed wihin he nework. Based on he high symmery of he CANH and CANL signals, he TLE7250V provides a very low level of elecromagneic emission (EME) wihin a wide frequency range. The TLE7250V is available in a small, leadless PG-TSON-8 package and in a PG-DSO-8 package. Boh packages are RoHS complian and halogen free. Addiionally he PG-TSON-8 package suppors he solder join requiremens for auomaed opical inspecion (AOI). The TLE7250VLE and he are fulfilling or exceeding he requiremens of he ISO11898-2. The TLE7250V provides a digial supply inpu V IO and a power-save mode. I is designed o fulfill he enhanced physical layer requiremens for CAN FD and suppors daa raes up o 2 MBi/s. On he basis of a very low leakage curren on he HS CAN bus inerface he TLE7250V provides an excellen passive behavior in power-down sae.

Funcional Descripion 4 Funcional Descripion HS CAN is a serial bus sysem ha connecs microconrollers, sensors and acuaors for real-ime conrol applicaions. The use of he Conroller Area Nework (abbreviaed CAN) wihin road vehicles is described by he inernaional sandard ISO 11898. According o he 7-layer OSI reference model he physical layer of a HS CAN bus sysem specifies he daa ransmission from one CAN node o all oher available CAN nodes wihin he nework. The physical layer specificaion of a CAN bus sysem includes all elecrical and mechanical specificaions of a CAN nework. The CAN ransceiver is par of he physical layer specificaion. Several differen physical layer sandards of CAN neworks have been developed in recen years. The TLE7250V is a High Speed CAN ransceiver wihou a wake-up funcion and defined by he inernaional sandard ISO 11898-2. 4.1 High Speed CAN Physical Layer TxD CANH CANL VIO VCC VIO = Digial supply volage VCC = Transmier supply volage TxD = Transmi daa inpu from he microconroller RxD = Receive daa oupu o he microconroller CANH = Bus level on he CANH inpu/oupu CANL = Bus level on he CANL inpu/oupu VDiff = Differenial volage beween CANH and CANL VDiff = VCANH VCANL VDiff VCC dominan receiver hreshold recessive receiver hreshold RxD VIO Loop(H,L) Loop(L,H) Figure 3 High speed CAN bus signals and logic signals Daa Shee 8 Rev. 1.0, 2015-08-12
Funcional Descripion The TLE7250V is a High-Speed CAN ransceiver, operaing as an inerface beween he CAN conroller and he physical bus medium. A HS CAN nework is a wo wire, differenial nework which allows daa ransmission raes for CAN FD frames up o 2 MBi/s. Characerisic for HS CAN neworks are he wo signal saes on he HS CAN bus: dominan and recessive (see Figure 3). V CC, V IO and GND are he supply pins for he TLE7250V. The pins CANH and CANL are he inerface o he HS CAN bus and operae in boh direcions, as an inpu and as an oupu. RxD and TxD pins are he inerface o he CAN conroller, he TxD pin is an inpu pin and he RxD pin is an oupu pin. The NEN pin is he inpu pin for he mode selecion (see Figure 4). By seing he TxD inpu pin o logical low he ransmier of he TLE7250V drives a dominan signal o he CANH and CANL pins. Seing TxD inpu o logical high urns off he ransmier and he oupu volage on CANH and CANL discharges owards he recessive level. The recessive oupu volage is provided by he bus biasing (see Figure 1). The oupu of he ransmier is considered o be dominan, when he volage difference beween CANH and CANL is a leas higher han 1.5 V (V Diff = V CANH - V CANL ). Parallel o he ransmier he normal-mode receiver moniors he signal on he CANH and CANL pins and indicaes i on he RxD oupu pin. A dominan signal on he CANH and CANL pins ses he RxD oupu pin o logical low, vice versa a recessive signal ses he RxD oupu o logical high. The normal-mode receiver considers a volage difference (V Diff ) beween CANH and CANL above 0.9 V as dominan and below 0.5 V as recessive. To be conform wih HS CAN feaures, like he bi o bi arbiraion, he signal on he RxD oupu has o follow he signal on he TxD inpu wihin a defined loop delay Loop 255 ns. The hresholds of he digial inpus (TxD and NEN) and also he RxD oupu volage are adaped o he digial power supply V IO. Daa Shee 9 Rev. 1.0, 2015-08-12
Funcional Descripion 4.2 Modes of Operaion The TLE7250V suppors wo differen modes of operaion, power-save mode and normal-operaing mode while he ransceiver is supplied according o he specified funcional range. The mode of operaion is seleced by he NEN inpu pin (see Figure 4). V CC = don care V IO > V IO(UV,R) power-save mode NEN = 1 NEN = 0 NEN = 1 V CC > V CC(UV,R) V IO > V IO(UV,R) normal-operaing mode NEN = 0 Figure 4 Mode sae diagram 4.2.1 Normal-operaing Mode In normal-operaing mode he ransmier and he receiver of he HS CAN ransceiver TLE7250V are acive (see Figure 1). The HS CAN ransceiver sends he serial daa sream on he TxD inpu pin o he CAN bus. The daa on he CAN bus is displayed a he RxD pin simulaneously. A logical low signal on he NEN pin selecs he normal-operaing mode, while he ransceiver is supplied by V CC and V IO (see Table 2 for deails). 4.2.2 Power-save Mode The power-save mode is an idle mode of he TLE7250V wih opimized power consumpion. In power-save mode he ransmier and he normal-mode receiver are urned off. The TLE7250V can no send any daa o he CAN bus nor receive any daa from he CAN bus. The RxD oupu pin is permanenly high in he power-save mode. A logical high signal on he NEN pin selecs he power-save mode, while he ransceiver is supplied by he digial supply V IO (see Table 2 for deails). In power-save mode he bus inpu pins are no biased. Therefore he CANH and CANL inpu pins are floaing and he HS CAN bus inerface has a high resisance. The undervolage deecion on he ransmier supply V CC is urned off, allowing o swich off he V CC supply in power-save mode. Daa Shee 10 Rev. 1.0, 2015-08-12
Funcional Descripion 4.3 Power-up and Undervolage Condiion By deecing an undervolage even, eiher on he ransmier supply V CC or he digial supply V IO, he ransceiver TLE7250V changes he mode of operaion. Turning off he digial power supply V IO, he ransceiver powers down and remains in he power-down sae. While swiching off he ransmier supply V CC, he ransceiver eiher changes o he forced power-save mode, or remains in power-save mode (deails see Figure 5).

Funcional Descripion 4.3.1 Power-down Sae Independen of he ransmier supply V CC and of he NEN inpu pin, he TLE7250V is in power-down sae when he digial supply volage V IO is urned off (see Figure 5). In he power-down sae he inpu resisors of he receiver are disconneced from he bus biasing V CC /2. The CANH and CANL bus inerface of he TLE7250V is floaing and acs as a high-impedance inpu wih a very small leakage curren. The high-ohmic inpu does no influence he recessive level of he CAN nework and allows an opimized EME performance of he enire HS CAN nework (see also Table 2). 4.3.2 Forced Power-save Mode The forced power-save mode is a fail-safe mode o avoid any disurbance on he HS CAN bus, while he TLE7250V faces a loss of he ransmier supply V CC. In forced power-save mode, he ransmier and he normal-mode receiver are urned off and herefore he ransceiver TLE7250V can no disurb he bus media. The RxD oupu pin is permanenly se o logical high. The bus biasing is floaing (deails see Table 2). The forced power-save mode can only be enered when he ransmier supply V CC is no available, eiher by powering up he digial supply V IO only or by urning off he ransmier supply in normal-operaing mode. While he ransceiver TLE7250V is in forced power-save mode, swiching he NEN inpu o logical high riggers a mode change o power-save mode (see Figure 5). 4.3.3 Power-up The HS CAN ransceiver TLE7250V powers up if a leas he digial supply V IO is conneced o he device. By defaul he device powers up in power-save mode, due o he inernal pull-up resisor on he NEN pin o V IO. In case he device needs o power-up o normal-operaing mode, he NEN pin needs o be pulled acive o logical low and he supplies V IO and V CC have o be conneced. By supplying only he digial power supply V IO he TLE7250V powers up eiher in forced power-save mode or in power-save mode, depending on he signal of he NEN inpu pin (see Figure 5).

Funcional Descripion 4.3.4 Undervolage on he Digial Supply V IO If he volage on V IO supply inpu falls below he hreshold V IO < V IO(UV,F), he ransceiver TLE7250V powers down and changes o he power-down sae. The undervolage deecion on he digial supply V IO has he highes prioriy. I is independen of he ransmier supply V CC and also independen of he currenly seleced operaing mode. An undervolage even on V IO always powers down he TLE7250V. ransmier supply volage VCC = don care VIO VIO undervolage monior VIO(UV,F) hyseresis VIO(UV,H) VIO undervolage monior VIO(UV,R) Delay(UV) delay ime undervolage any mode of operaion power-down sae sand-by mode NEN X = don care high due he inernal pull-up resisor 1) 1) assuming no exernal signal applied Figure 6 Undervolage on he digial supply V IO Daa Shee 13 Rev. 1.0, 2015-08-12
Funcional Descripion 4.3.5 Undervolage on he Transmier Supply V CC In case he ransmier supply V CC falls below he hreshold V CC < V CC(UV,F), he ransceiver TLE7250V changes he mode of operaion o forced power-save mode. The ransmier and also he normal-mode receiver of he TLE7250V are powered by he V CC supply. In case of an insufficien V CC supply, he TLE7250V can neiher ransmi he CANH and CANL signals correcly o he bus, nor can i receive hem properly. Therefore he TLE7250V blocks he ransmier and he receiver in forced power-save mode (see Figure 7). The undervolage deecion on he ransmier supply V CC is only acive in normal-operaing mode (see Figure 5). digial supply volage VIO = on VCC VCC undervolage monior VCC(UV,F) hyseresis VCC(UV,H) VCC undervolage monior VCC(UV,R) Delay(UV) delay ime undervolage normal-operaing mode forced sand-by mode normal-operaing mode NEN Assuming he NEN remains low. The low signal is driven by he exernal microconroller Figure 7 Undervolage on he ransmier supply V CC 4.3.6 Volage Adapion o he Microconroller Supply The HS CAN ransceiver TLE7250V has wo differen power supplies, V CC and V IO. The power supply V CC supplies he ransmier and he normal-mode receiver. The power supply V IO supplies he digial inpu and oupu buffers and i is also he main power domain for he inernal logic. To adjus he digial inpu and oupu levels of he TLE7250V o he I/O levels of he exernal microconroller, connec he power supply V IO o he microconroller I/O supply volage (see Figure 13). Noe: In case he digial supply volage V IO is no required in he applicaion, connec he digial supply volage V IO o he ransmier supply V CC. Daa Shee 14 Rev. 1.0, 2015-08-12
Fail Safe Funcions 5 Fail Safe Funcions 5.1 Shor Circui Proecion The CANH and CANL bus oupus are shor circui proof, eiher agains GND or a posiive supply volage. A curren limiing circui proecs he ransceiver agains damages. If he device is heaing up due o a coninuous shor on he CANH or CANL, he inernal overemperaure proecion swiches off he bus ransmier. 5.2 Unconneced Logic Pins All logic inpu pins have an inernal pull-up resisor o V IO. In case he V IO supply is acivaed and he logical pins are open, he TLE7250V eners ino he power-save mode by defaul. In power-save mode he ransmier of he TLE7250V is disabled and he bus bias is floaing. 5.3 TxD Time-ou Funcion The TxD ime-ou feaure proecs he CAN bus agains permanen blocking in case he logical signal on he TxD pin is coninuously low. A coninuous low signal on he TxD pin migh have is roo cause in a locked-up microconroller or in a shor circui on he prined circui board, for example. In normal-operaing mode, a logical low signal on he TxD pin for he ime > TxD enables he TxD ime-ou feaure and he TLE7250V disables he ransmier (see Figure 8). The receiver is sill acive and he daa on he bus coninues o be moniored by he RxD oupu pin.

A permanen low signal on he TxD inpu pin acivaes he TxD ime-ou funcion and deacivaes he ransmier. To release he ransmier afer a TxD ime-ou even he TLE7250V requires a signal change on he TxD inpu pin from logical low o logical high. Daa Shee 15 Rev. 1.0, 2015-08-12

The overemperaure proecion is acive in normal-operaing mode and disabled in power-save mode. In case of an overemperaure condiion, he emperaure sensor will disable he ransmier (see Figure 1) while he ransceiver remains in normal-operaing mode.

Applicaion Informaion 8.3 Examples for Mode Changes Changing he saus on he NEN inpu pin riggers a change of he operaing mode, disregarding he acual signal on he CANH, CANL and TxD pins (see also Chaper 4.2). Mode changes are riggered by he NEN pin, when he device TLE7250V is fully supplied. Seing he NEN pin o logical low changes he mode of operaion o normal-operaing mode: The mode change is execued independenly of he signal on he HS CAN bus. The CANH, CANL inpus may be eiher dominan or recessive. They can be also permanenly shored o GND or V CC. A mode change is performed independenly of he signal on he TxD inpu. The TxD inpu may be eiher logical high or low. Analog o ha, changing he NEN inpu pin o logical high changes he mode of operaion o he power-save mode independen on he signals a he CANH, CANL and TxD pins. Noe: In case he TxD signal is low seing he NEN inpu pin o logical low changes he operaing mode of he device o normal-operaing mode and drives a dominan signal o he HS CAN bus. Noe: The TxD ime-ou is only effecive in normal-operaing mode. The TxD ime-ou imer sars when he TLE7250V eners normal-operaing mode and he TxD inpu is se o logical low.

Applicaion Informaion 8.3.1 Mode Change while he TxD Signal is low The example in Figure 14 shows a mode change o normal-operaing mode while he TxD inpu is logical low. The HS CAN signal is recessive, assuming all oher HS CAN bus subscribers are also sending a recessive bus signal. While he ransceiver TLE7250V is in power-save mode, he ransmier and he normal-mode receiver are urned off. The TLE7250V drives no signal o he HS CAN bus nor does i receive any signal from he HS CAN bus. Changing he NEN o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu signal remains logical low. The ransmier and he normal-mode receiver remain disabled unil he mode ransiion is compleed. In normal-operaing mode he ransmier and he normal-mode receiver are acive. The low signal on he TxD inpu drives a dominan signal o he HS CAN bus and he RxD oupu becomes logical low following he dominan signal on he HS CAN bus. Changing he NEN pin back o logical high, disables he ransmier and normal-mode receiver again. The RxD oupu pin is blocked and se o logical high wih he sar of he mode ransiion. The TxD inpu and he ransmier are blocked and he HS CAN bus becomes recessive.

Applicaion Informaion 8.3.2 Mode Change while he Bus Signal is dominan The example in Figure 15 shows a mode change while he bus is dominan and he TxD inpu signal is se o logical high. While he ransceiver TLE7250V is in power-save mode, he ransmier and he normal-mode receiver are urned off. The TLE7250V drives no signal o he HS CAN bus nor does i receive any signal from he HS CAN bus. Changing he NEN o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu signal remains logical high. The ransmier and he normal-mode receiver remain disabled unil he mode ransiion is compleed. In normal-operaing mode he ransmier of TLE7250V remains recessive, because of he logical high signal on he TxD inpu. The normal-mode receiver becomes acive and he RxD oupu signal changes o logical low following he dominan signal on he HS CAN bus. Changing he NEN pin back o logical high, disables he ransmier and normal-mode receiver again. The RxD oupu pin is blocked and se o logical high wih he sar of he mode ransiion.
