200V IC for Automotive Powertrain and Battery Management 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 3.3V, 5V 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.
