HVIC and latch immune CMOS technologies enable rugged monolithic construction. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise immunity is achieved with low di/dt peak of the gate drivers. VOFFSET 600 V Max Duty cycle 50% Driver source/sink current 180 mA/260 mA typ. Vclamp 15.4 V typ. Deadtime 1.1 µs typ.
