Introduction
The IRS21091 is a new HVIC product that replaces the IR21091 HVIC and is pin-to-pin
compatible with its predecessor. In many cases, little or no change is necessary to use
the new product. This application note describes the differences between the IRS21091
and the IR21091 HVICs.
The IRS21091 is a high voltage, high speed power MOSFET and IGBT driver with
dependent high- and low-side referenced output channels. Proprietary HVIC and latch
immune CMOS technologies enable ruggedized monolithic construction. The logic input
is compatible with standard CMOS or LSTTL output, down to 3.3 V logic. The output
drivers feature a high pulse current buffer stage designed for minimum driver crossconduction. 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 V.

With the IRS21091,
1. The VIH is reduced to 2.5 V for better 3.3 V logic compatibility.
2. The VOH and VOL are tested using a new standardized test condition of IO =2 mA.
The output driver’s on resistance is lower for IRS21091, which improves
immunity against the Miller effect.
3. The typical values for IO+ and IO- are increased, which allows faster switching.
