Description
The IRS21956 is high voltage and programmable ramp slope control gate driver for MOSFET and IGBT with
single low side dual mode driver, high side driver and floating 5V input. Proprietary HVIC and latch immune
CMOS technologies enable ruggedized monolithic construction. The floating logic input is compatible with
standard 5V CMOS or LSTTL output. The output driver features a programmable slope control by external
R/C and input signals. The floating channels can be used to drive an N-channel power MOSFET or IGBT in
the high side configuration, which operates up to 600 volts above the COM ground.
