Description
The AUIRS2123S/AUIRS2124S are high voltage, high speed power MOSFET and IGBT drivers.
Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The
logic input is compatible with standard CMOS outputs. The output drivers feature a high pulse current
buffer stage designed for minimum cross-conduction. 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.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to GND, all currents are defined positive into any
lead. This is a stress only rating and operation of the device at these or any conditions exceeding those
indicated in the operational sections of this specification is not implied
