Description

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

Packages

gate drive voltage. An open drain

signal is pro-

FAULT

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.
