The IRS21952 contains 2 low side outputs sharing common ground and 1 high side output. Low side drivers can tolerate up to -600 V below input signal (VSS: input supply return). High side driver can tolerate up to 600 V above low side ground (COM: low side supply return). The IRS21952 has better propagation delay and thermal characteristics compared to a photo-coupler driver. The logic inputs are compatible with standard CMOS or LSTTL output. Proprietary HVIC and latch-up immune CMOS technologies enable ruggedized monolithic construction.
