Description
The IR2112 is an independent high and low-side referenced output channel high voltage, high-speed power MOSFET and IGBT driver. Ruggedized monolithic construction is made possible by proprietary HVIC and latches immune CMOS technology. Down to 3.3V logic, logic inputs are compatible with typical CMOS or LSTTL outputs.
A high pulse current buffer stage with minimal driver cross-conduction is a feature of the output drivers. To make use in high-frequency applications simpler, propagation delays are matched. An N-channel power MOSFET or IGBT that operates up to 600 volts can be driven via the floating channel in a high-side configuration.
