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
FAULT
signal 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.
