Description

Packages

The IR2127/IR2128/IR21271/IR21281(S) is a high

voltage, high speed power MOSFET and IGBT driver.

Proprietary HVIC and latch immune CMOS technolo-

gies 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

signal is provided 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.
