AUIRS4427S driver IC

From International Rectifier comes the AUIRS4427S dual low-side driver IC for low- mid- and high-voltage automotive applications including general purpose motor drives, automotive DC/DC converters and hybrid powertrain drives.

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 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," said Henning Hauenstein, VP of IR's automotive products.

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.

Available in an 8-pin SOIC package, pricing for the AUIRS4427S begins at $0.51 each in 100,000-unit quantities. Production orders are available immediately. The automotive-qualified device is Pb-free and RoHS-compliant. Prices are subject to change.
