1 FULLY PROTECTED POWER MOSFET SWITCH General Descripion: Raing Summary: Provisional Daa Shee No.PD A The IRSF3010 is a hree erminal monolihic SMART POWER MOSFET wih buil in shor circui, over-emperaure, ESD and over-volage proecions. The on chip proecion circui laches off he POWER MOSFET in case he drain curren exceeds 14A (ypical) or he juncion emperaure exceeds 165 C (ypical) and keeps i off unil he inpu is driven low. The drain o source volage is acively clamped a 55V (ypical), prior o he avalanche of POWER MOSFET, hus improving is performance during urn off wih inducive loads. The inpu curren requiremens are very low (300uA) which makes he IRSF3010 compaible wih mos exising designs based on sandard POWER MOSFETs.

10 Applicaion Informaion Inroducion Proeced monolihic POWER MOSFETs offer simple, cos effecive soluions in applicaions where exreme operaing condiions can occur. The margin beween he operaing condiions and he absolue maximum values can be narrowed resuling in beer uilizaion of he device and lower cos. ESD proecion also reduces he off-circui failures during handling and assembly. General Descripion The IRSF3010 is a fully proeced monolihic N-channel, logic level POWER MOSFET wih 80mΩ (max) on-resisance. The buil-in proecions include overcurren, over-emperaure, ESD and acive over-volage proecions. The over-curren and over-emperaure proecion makes he IRSF3010 indesrucible a any load condiions in swiching or in linear applicaions. The buil-in ESD proecion minimizes he risk of ESD damage when he device is off-circui. The IRSF3010 is fully characerized for avalanche operaion and can be used for fas de-energizaion of inducive loads. The IRSF3010 Inelligen Power Swich ha is available in he TO220 package offers an easy upgrade from non-proeced devices. Block Diagram The zener diode beween he inpu and he source (see figure 20) provides he ESD proecion for he inpu and also limis he applicable volage o he inpu o 10V. The R-S flip-flop memorizes he occurrence of an error condiion and conrols he Q2 and Q3 swiches. The flip-flop can be cleared by holding he inpu low for he specified minimum duraion. COMP1 and COMP2 comparaors are used o compare he over-curren and over-emperaure signals wih he buil-in reference. Eiher comparaor can rese he faul flip-flop and urn Q1 off. During faul condiion, Q2 disconnecs gae of Q1 from he inpu, Q3 shors he gae and source of Q1, resuling in rapid urn-off of Q1. The zener diode beween he gae and drain of Q1 urns Q1 on, when he drain o source volage exceeds 55V. Swiching Characerisics In he IRSF3010 he conrol logic and he proecion circuis are powered from he inpu pin. When posiive volage appears a he inpu pin he R-S flip-flop urns Q2 on and connecs he gae of he main device o he inpu. The urn-on speed is limied by he channel resisance of Q2 and he gae charge requiremens of Q1. The ypical swiching waveforms a 5V inpu volage are shown in figure 21. Using higher inpu volage will improve he urn-on ime bu i does no affec he urnoff swiching speed. Inpu volage 5V/ Drain volage 5V/ 10 Fig.20 Block Diagram Drain Curren: 1A/div. Time: 1µsV/div.

11 The ypical waveforms a 7V inpu volage are shown in figure 22. In ypical swiching applicaions, below 40kHz, he difference in swiching losses beween he IRSF3010 and he same size sandard MOSFET is negligible. Inpu volage 5V/ Drain volage 5V/ Drain Curren: 1A/ The ypical waveforms a over-curren shu-down are shown in figure 23. Afer urn-on he curren in he inducor a he drain sars ramping up.

The IRSF3010 swiches a 1Ω resisive load o a 12V power supply. When he hermal balance is esablished he juncion emperaure is limied on pulse by pulse basis. Inpu volage 10V/div. Drain volage 5V/div. Time: 1µsV/div. Fig. 22 Swiching waveforms wih 7V Inpu volage Over-curren Proecion When he drain curren exceeds he prese limi he proecion circui reses he inernal flip-flop and urns Q1 off. The normal operaion can be resored by holding he inpu volage below he specified hreshold level (approx. 1.3V) for he specified minimum rese ime. Inpu volage 5V/div. Drain Curren: 2A/div.

Fig. 24 Over-emperaure shu-down Over-volage Proecion When he drain o source volage exceeds 55V he zener diode beween gae and drain urns he IRSF3010 on, before he breakdown volage of he drain-source diode is reached. This grealy enhances he energy he device can wihsand safely during urnoff of inducive loads compared o avalanche breakdown. Thus he device can be used for fas deenergizaion of inducive loads. The absorbed energy is limied only by he maximum juncion emperaure. Time: 10µsV/div.
