Enhanced Protection, Diagnostics for Automotive Relay Replacements and Battery Switches

Enhanced Protection, Diagnostics for Automotive Relay Replacements and Battery Switches


The automotive-qualified AUIR3200S MOSFET driver IC from International Rectifier incorporates 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 0.75mΩ can be achieved.

The AUIR3200S not only offers protection and diagnostic features to enhance system reliability but also delivers a high-side protected switch with lowest RDS(ON) in the market when designed in conjunction with high performance automotive power MOSFETs.

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.

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