IR Introduces 200V IC For Automotive Powertrain & Battery Management Applications

May 13, 2009 by Jeff Shepard

International Rectifier, (IR)® introduced the AUIRS2003S 200V IC for low- mid- and high-voltage automotive applications including automotive pre-charge switch and stepper drives and dc-dc converters.

Qualified to AEC-Q100 standards, the AUIRS2003S is a rugged, flexible high speed power MOSFET driver with dependent high- and low-side referenced output channels tailored for use in harsh automotive environments and under-the-hood applications. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction while the floating channel can be used to drive an N-channel power MOSFET in the high-side configuration operating up to 200V. The new device also offers low quiescent current that enables a low-cost bootstrap power supply for the high-side circuitry.

"With its host of protection features, the AUIRS2003S is designed to provide a rugged and flexible driver IC solution specifically designed to meet the challenge of automotive powertrain and battery management applications," said Henning Hauenstein, Vice President of IR’s Automotive Products.

The AUIRS2003S features high-side output in phase with the input signal and low-side output out of phase with the input signal. The new device accepts input logic levels of 3.3, 5 and 15V with standard CMOS or LSTTL outputs and offers a comprehensive set of protection features including under-voltage lockout (UVLO), deadtime protection, and negative voltage spike (Vs) immunity to protect against catastrophic events during high-current switching and short circuit conditions.

The new device utilizes 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.

Offered in an 8-pin SOIC package, pricing for the AUIRS2003S begins at US $0.55 each in 100,000-unit quantities. Production orders are available immediately. The automotive-qualified device is lead-free and RoHS compliant.
