AUIR2085S Self-oscillating Halfbridge Driver The AUIR2085S is a rugged, general purpose high speed selfoscillating 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 ruggedized monolithic construction and an industry benchmarking negative voltage spike immunity for fail proof operation even under extreme switching conditions and PRESS RELEASE DATA SHEET HI-RES GRAPHIC Automotive HOME PAGE short circuit events. Features • • • • • • • • • • • Simple primary side control solution to enable half-bridge DC-Bus converters for 48V distributed systems with reduced component count and board space. Integrated 50% duty cycle oscillator and half-bridge driver IC in a single SO-8 package Programmable switching frequency with up to 500 kHz max per channel +/- 1A drive current capability optimized for low charge MOSFETs Adjustable dead-time 50ns – 200ns Floating channel designed for bootstrap operation up to +100Vdc High and low side pulse width matching to +/-25ns Adjustable over-current protection Under-voltage lockout and internal soft start Lead-free, RoHS compliant Automotive qualified Advantages • The AUIR2085S is a self oscillating half-bridge driver IC with 50% duty cycle ideally suited for 36V-75V. • The AUIR2085S initiates a soft start at power up and after every over-current condition. Under-voltage lockout prevents operation if VCC is less than 7.5V. • The IC is qualified according to AEC-Q100 standards and features an environmentally friendly, lead-free and RoHS compliant bill of material and are part of International Rectifier’s Zero-Defect initiative. • The AUIR2085S is set up to be in line with typical change management requirements of the automotive market.
