Data Sheet No. PD60029 revj I2155&(PbF) (NOTE: For new designs, we recommend I s new products I2153 and I21531) SELF-OSCILLATING HALF-BIDGE DIE Features Floating channel designed for bootstrap operation Fully operational to +600 Tolerant to negative transient voltage d/dt immune Undervoltage lockout Programmable oscillator frequency Description 1 f = 1.4 ( + 150 Ω) C Typical Connection T Matched propagation delay for both channels Micropower supply startup current of 125 µa typ. Low side output in phase with T Available in Lead-Free The I2155 is a high voltage, high speed, selfoscillating power MOSFET and IGBT driver with both high and low side referenced output channels. Proprietary HIC and latch immune CMOS technologies enable ruggedized monolithic construction. The front end features a programmable oscillator which is similar to the 555 timer. The output drivers feature a high pulse current buffer stage and an internal deadtime designed for minimum driver crossconduction. Propagation delays for the two channels are matched to simplify use in 50% duty cycle applications. The floating channel can be used to drive an N-channel power T Product Summary OFFSET 600 max.

Therefore, the IC supply voltage is normally derived by forcing current into the supply lead (typically by means of a high value resistor connected between the chip and the rectified line voltage and a local decoupling capacitor from to COM) and allowing the internal zener clamp circuit to determine the nominal supply voltage. Therefore, this circuit should not be driven by a DC, low impedance power source of greater than CLAMP. 2 www.irf.com
