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.
