AUIRS4426S driver IC

International Rectifier has released the AUIRS4426S dual-channel, low-side driver IC for use in automotive applications including hybrid powertrain drives, direct fuel injection and DC/DC converter applications.

Available in an 8-lead SOIC package, the automotive-qualified AUIRS4426S is a rugged low-voltage, high-speed power MOSFET and IGBT driver that features matched propagation delay for both channels to help simplify design.

"With its ruggedized monolithic construction, the AUIRS4426S is particularly well suited to HEV applications that require a rugged and flexible solution," said Marzak Li, product marketing manager, IR's automotive products business unit.

The AUIRS4426S features a gate drive supply range from 6V to 20V, CMOS Schmitt-triggered inputs, outputs out-of-phase with inputs, and input logic is active low.

The device is qualified according to AEC-Q100 standards, features an environmentally friendly, lead-free and RoHS compliant bill of materials, and is part of IR's automotive quality initiative targeting zero defects.

Pricing for the AUIRS4426S 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.
