The IR2127/IR2128/IR21271(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-cur-
rent 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 oc-
curred. 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-chan-
nel power MOSFET or IGBT in the high side or low
side configuration which operates up to 600 volts.
