Intelligent Power Switches suit automotive environments.
January 6, 2010 -
Intended for harsh 24 V automotive environments, such as under-the-hood truck junction boxes, AUIPS7121R and AUIPS7141R are 65 V high-side switches with current-sensing and built-in protection. Each can sustain several millions of cycles under short-circuit conditions and incorporates over-current shutdown, over-temperature shutdown, and active clamp circuits. Qualified to AEC-Q100, RoHS-compliant switches provide accurate current feedback of ±5% over full operating temperature range.

IR Introduces Rugged, Reliable AUIPS7121R and AUIPS7141R Intelligent Power Switches for Harsh 24V Automotive Environments
EL SEGUNDO, Calif. - International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the AUIPS7121R and AUIPS7141R 65V high-side intelligent power switches (IPS) with accurate current-sensing and built-in protection circuits for harsh 24V automotive environments such as under-the-hood truck junction boxes.
The AUIPS7121R and AUIPS7141R offer a comprehensive set of protection features to ensure safe reliable switching. Moreover, the new devices' over-current shutdown, over-temperature shutdown and active clamp circuit assure safe operation and protection under repetitive short circuit conditions.
"Engineers face a major hurdle designing truck junction boxes that meet tough new performance standards under short-circuit conditions. As a result of its protection features, the AUIPS71xx family can operate for extended periods of time, sustaining several millions of cycles under short-circuit conditions to provide a reliable robust solution for harsh 24V automotive environments such as under-the-hood junction boxes," said David Jacquinod, product marketing manager, IR's Automotive Business Unit.
In addition to a host of protection features, the AUIPS71xx family provides an accurate current feedback of +/- 5% over the entire operating temperature range while turn-on and off-time are optimized to minimize noise in EMI sensitive automotive applications.
The devices are qualified according to AEC-Q100 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR's automotive quality initiative targeting zero defects.
