MOSFET driver suits automotive apps

International Rectifier has unveiled the AUIRS2016S high-voltage power MOSFET high-side driver for automotive gate drive applications including common injection rails, diesel and gasoline direct injection applications and solenoid drivers.

The AUIRS2016S features an internal Vs-to-GND recharge NMOS. The device's output driver features a 250mA high pulse current buffer stage. The channel can be used to drive an n-channel power MOSFET in the high-side configuration, operating up to 150V above ground. It also offers negative voltage spike immunity (-Vs) to protect against catastrophic events during high-current switching and short circuit conditions.

"The AUIRS2016S is a robust, highly reliable IC designed to meet the rugged performance needs of automotive under-the-hood motor control units, targeting energy-efficient applications such as diesel and gasoline direct fuel injection systems," said Henning Hauenstein, VP and general manager of the automotive products business unit at IR.

Qualified to AEC-Q100 standards, the AUIRS2016S also offers 5V compatible logic level inputs, one high-side output and internal low side Vs recharge, CMOS Schmitt trigger inverted input with pull up resistor and CMOS Schmitt trigger inverted reset with pull down resistor.

The new device uses IR's advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.

Pricing for the AUIRS2016S begins at $0.98 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.
