Introduction
The IRS2011 is a new HVIC product that replaces the IR2011 and is pin-to-pin compatible
with its predecessor. This application note describes the various differences between the
IRS2011 and the IR2011 HVICs.
The IRS2011 is a high power, high speed power MOSFET driver with independent high
and low side referenced output channels, ideal for Class D Audio and DC-DC converter
applications. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to
3.0 V logic. The output drivers feature a high pulse current buffer stage designed for
minimum driver cross-conduction. Propagation delays are matched to simplify its use in
high frequency applications. The floating channel can be used to drive an N-channel
power MOSFET in the high side configuration which operates up to 200 V. Proprietary
HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.
