International Rectifier introduced 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 (Vs) immunity is provided to protect against catastrophic events during high-current switching and short circuit conditions.
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 US $0.51 each in 100,000-unit quantities. Production orders are available immediately. The automotive-qualified device is lead-free and RoHS compliant. Prices are subject to change.
