Product Summary

The IRS21956S is a 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 of the IRS21956S 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.
