Dual driver IC

International Rectifier has introduced the AUIRS4427S dual low-side driver IC for low-, mid- and high-voltage motor vehicle applications including general-purpose motor drives, vehicle DC-DC converters and hybrid powertrain drives.

The device 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 immunity is provided to protect against catastrophic events during high-current switching and short-circuit conditions.

The MOSFET, which is 3.3 and 5 V logic compatible with standard CMOS or LSTTL output, features gate voltage (VOUT) up to 20, CMOS Schmitt-triggered inputs, two independent gate drivers and outputs in phase with inputs.
