IR2112(-1-2)(S)PbF
Description
The IR2112(S) 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, down to 3.3V logic.
The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction.
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.
