Features

Description

The IRS21851 is a high voltage, high speed power

MOSFET and IGBT single high-side driver with propa-

gation delay matched output channels. Proprietary

HVIC and latch immune CMOS technologies enable

ruggedized monolithic construction. The floating logic

input is compatible with standard CMOS or LSTTL

output, down to 3.3 V logic and can be operated up to

600 V above the ground. The output driver features a

high pulse current buffer stage designed for mini-

mum driver cross-conduction. The floating channel

can be used to drive an N-channel power MOSFET

or IGBT in the high- side configuration, which oper-

ates up to 600 V.
