The IR2127 is a high voltage, high speed power
MOSFET and IGBT driver. Proprietary HVIC and
latch immune CMOS technologies enable rugge-
dized monolithic construction. The logic input is
compatible with standard CMOS or LSTTL outputs.
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-
conduction. 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.
