The IR2011 is a high-power, high-speed power MOSFET driver with a separate high-low side reference output channel. Logic input compatible with standard CMOS or LSTTL output, as low as 3.0V logic. The output driver has a high pulse current buffer stage designed for minimal driver cross conduction. Propagation delay matching to simplify use in high frequency applications.
A floating channel can be used to drive a high-side configuration of N-channel power mosFETs that operate at up to 200 volts. Proprietary HVIC and latch-immune CMOS technology enable a rugged overall structure.
