Description

The IR2122(S) is a high voltage, high speed power

MOSFET and IGBT driver.Proprietary HVIC and latch

immune CMOS technologies enable ruggedized

monolithic construction.The logic input is compatible

with standard CMOS or LSTTL outputs, down to

3.3V. The protection circuity detects over-current in

the driven power transistor and terminates the gate

drive voltage. An open drain FAULTsignal is pro-

vided to indicate that an over-current shutdown has

occurred. The output driver features a high pulse

current buffer stage designed for minimum cross-con-

duction.The floating channel can be used to drive an

N-channel power MOSFET or IGBT in the high side

or low side configuration which operates up to 600

volts.
