Description
The IR2112 is a high voltage, high speed power
MOSFET and IGBT driver with independent high and
low side referenced output channels. Proprietary HVIC
and latch immune CMOS technologies enable rugge-
dized monolithic construction. Logic inputs are com-
patible with standard CMOS or LSTTL outputs. The
output drivers feature a high pulse current buffer stage
designed for minimum driver cross-conduction. Propa-
gation delays are matched to simplify use in high fre-
quency applications. The floating channel can be used
to drive an N-channel power MOSFET or IGBT in the
high side configuration which operates up to 600 volts.
