MOSFET driver IC offers enhanced protection and diagnostics for automotive relay replacements and battery switches

February 21, 2013 // By Paul Buckley
International Rectifier has introduced the automotive-qualified AUIR3200S MOSFET driver IC with comprehensive protection and diagnostic features offering enhanced reliability for relay replacements and battery switch applications.

Available in an SO8 package, the AUIR3200S features over-current protection and over-temperature protection in addition to a diagnostic feature to report a short on the load. When designed with two AUIRLS3034-7P power MOSFETs, an on-state resistance (Rds(on)) as low as 0.75 mohm can be achieved.

The new device is qualified according to AEC-Q100 standards, features an environmentally friendly, lead-free and RoHS compliant bill of materials, and is part of IR’s automotive quality initiative targeting zero defects.

Availability and Pricing

Pricing for the AUIR3200S begins at $0.65 each in 100,000-unit quantities. Production orders are available immediately.
