IR Introduces AUIRS2003S 200V IC

17 JUNE 2009

International Rectifier has launched 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. The AUIRS2003S features high-side output in phase with the input signal and low-side output out of phase with the input signal. The 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. It 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.
