IRS21856S
Description
The IRS21856 is high voltage and programmable ramp slope control gate driver for MOSFET and IGBT with
single high side dual mode driver and low side driver.
Proprietary HVIC and latch immune CMOS
technologies enable ruggedized monolithic construction. The logic input is compatible with 5V standard
CMOS or LSTTL output. The output driver features a programmable slope control by external R/C and input
signal. 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.
