IR Introduces Highly Integrated AUIR3330S Intelligent Power Switch with Active di/dt control for Automotive Motor Control

EL SEGUNDO, Calif.--(BUSINESS WIRE)--International Rectifier, IR® (NYSE:IRF), a world leader in power management technology, today introduced the AUIR3330S Intelligent Power Switch (IPS) with a proprietary active di/dt control feature that significantly reduces conducted EMI and switching losses to simplify design and reduce overall system cost in automotive motor drive applications.

“IR’s innovative active di/dt control drastically reduces conducted EMI on the input supply without increasing switching losses, enabling a reduction in the size of the EMI filter and the heat sink for more efficient compact motor systems”

The new 40 V high-side device combines bootstrap regulator, charge pump and high-side driver into a single package to offer a highly integrated solution. The load can be driven up to 40 kHz at 100 percent of 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 AUIR3330S also features current sensing feedback, a diagnostic function, very low current consumption in sleep mode and ESD protection.

“IR’s innovative active di/dt control drastically reduces conducted EMI on the input supply without increasing switching losses, enabling a reduction in the size of the EMI filter and the heat sink for more efficient compact motor systems,” said David Jacquinod, product marketing manager, IR’s Automotive Products Business Unit.

The 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.
