International Rectifier AUIR3240S battery power switch

Monday, 23 April, 2012 | Supplied by: Avnet Electronics Marketing

The motor vehicle-qualified AUIR3240S battery power switch for the combustion-engine shut-off and restart function (stop-start system) is claimed to help reduce fuel consumption by up to 15%.

The integrated boost converter is part of a system that requires a ‘board net stabiliser’ using a power switch that disconnects the starter and main battery from the auxiliary electrical systems during engine start.

The device can drive several MOSFETs in parallel to achieve low on-state resistance (RDS(on)) with current consumption below 50 µA.

The converter provides 15 V on the output with a wide input voltage (4-36) and features diagnostics on the output current and a thermal sensor interface for robust designs.
