International Rectifier’s AUIR2085S is a rugged, general-purpose high-speed self-oscillating half-bridge driver which was specifically designed, tested and qualified for use in harsh environments such as automotive under-the-hood applications.
Proprietary HVIC technology enables ruggedised monolithic construction and excellent negative voltage spike immunity for failproof operation even under extreme switching conditions and short circuit events.
The device is a simple primary side control solution to enable half-bridge DC-bus converters for 48 V distributed systems. It integrates a 50% duty cycle oscillator and half-bridge driver IC in a single SO-8 package. Switching frequency is programmable up to 500 kHz per channel, and dead-time is adjustable between 50 and 200 ns. The chip’s ±1 A drive current capability is optimised for low-charge MOSFETs, while its floating channel design is suitable for bootstrap operation up to +100 V d.c. It initiates a soft start at power up and after every over-current condition. Under-voltage lockout prevents operation if VCC is less than 7,5 V.
