Descriptions
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.
