The AUIR2085S, an automotive-qualified control IC for low- mid- and high-voltage automotive drive applications, takes the form of a self-oscillating half-bridge 100V driver with a 50% duty cycle. The device integrates a soft-start capacitor that gradually increases duty cycle from zero to 50% for 5 ms to limit in-rush current during start up and maintains equal pulse widths for the high- and low-side MOSFETs throughout the start-up sequence. Other features include ±1A gate drive current optimized for low charge MOSFETs and adjustable dead time from 50 ns to 200 ns. Additionally, the AUIR2085S is qualified to AEC-Q100 standards and provides a programmable switching frequency up to 500 kHz. Available in an eight-pin SOIC package, pricing for the AUIR2085S begins at $1.71 each/100,000. For more information, contact Sian Cummins at INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7148.
