IR Introduces Automotive-Qualified Dual Low-Side Driver IC

The AUIRS4427S is a low-voltage, high speed power MOSFET and IGBT driver qualified to AEC-Q100 standards. The output drivers feature a high pulse current buffer stage for minimum driver cross-conduction and matched propagation delay for both channels. Negative voltage spike (Vs) immunity is provided to protect against catastrophic events during high-current switching and short circuit conditions.

With its benchmark negative voltage spike immunity and matched propagation delay, the AUIRS4427S is an extremely rugged dual low-side driver that enables fast switching speeds making the device ideally suited to high power DC-DC converters and powertrain applications.
The AUIRS4427S, which is 3.3V and 5V logic compatible with standard CMOS or LSTTL output, features gate voltage (VOUT) up to 20V, CMOS Schmitt-triggered inputs, two independent gate drivers, and outputs in phase with inputs.
