Automotive power switch

22 June 2011 Power Electronics / Power Management

New from International Rectifier is the AUIR3330S Intelligent Power Switch (IPS) with a proprietary active di/dt control feature designed to reduce conducted EMI and switching losses in automotive motor drive applications.

The 40 V high-side device combines bootstrap regulator, charge pump and high-side driver into a single package. The load can be driven up to 40 kHz at 100% duty cycle. Additionally, the AUIR3330S features programmable over-current and over-temperature protection required by applications operating in harsh automotive environments such as pumps and fans. The device also features current sensing feedback, a diagnostic function, very low current consumption in sleep mode and ESD protection.

The device is qualified according to AEC-Q100 standards and features a lead-free and RoHS compliant bill of materials.
