SINGLE HIGH SIDE DRIVER IC
Product Summary
V OFFSET 600 V max.
I O +/- 4A/ 4A
V OUT 10 V - 20 V
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.
