Description

The IR2127/IR2128/IR21271/IR21281 is a high volt-

age, high speed power MOSFET and IGBT driver.Pro-

prietary HVIC and latch immune CMOS technologies

enable ruggedized monolithic construction. The logic

input is compatible with standard CMOS or LSTTL out-

puts.The protection circuity detects over-current in the

driven power transistor and terminates the gate drive

voltage. An open drain

signal is provided to

FAULT

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.
