Packages
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
ruggedized monolithic construction. Logic inputs are
compatible with standard CMOS or LSTTL outputs.
The output drivers feature a high pulse current buffer
stage designed for minimum driver cross-conduc-
tion. Propagation delays are matched to simplify
use in high frequency 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.
