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
16-Lead SOIC
and latch immune CMOS technologies enable rugge-
14-Lead PDIP
(wide body)
dized monolithic construction. Logic inputs are com-
patible 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.
