PRESS RELEASE
AUIR2085S Self-oscillating Half-bridge Driver
DATA SHEET
The 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 ruggedized monolithic
construction and an industry benchmarking
negative voltage spike immunity for fail proof
operation even under extreme switching conditions
and 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
  Rectifiers Zero-Defect initiative.
• The AUIR2085S is set up to be in line with
  typical change management requirements of the
  automotive market.
