Power switches suit harsh automotive applications
An International Rectifier product story
Edited by the Electronicstalk editorial team Dec 23, 2009
International Rectifier has launched the AUIPS712R and AUIPS7141R 65V high-side intelligent power switches (IPS) with accurate current sensing and built-in protection circuits.
The switches have been developed for harsh 24V automotive environments such as under-the-hood truck junction boxes.
The AUIPS7121R and AUIPS7141R are said to offer a comprehensive set of protection features to ensure safe and reliable switching.
The devices' over-current shutdown, over-temperature shutdown and active clamp circuit are said to assure safe operation and protection under repetitive short-circuit conditions.
The AUIPS71xx family can operate for extended periods of time, sustaining several millions of cycles under short-circuit conditions to provide a robust solution for harsh 24V automotive environments.
The AUIPS71xx family also provides an accurate current feedback of +/- 5 per cent over the entire operating temperature range while turn-on and off-time are optimised to minimise noise in EMI-sensitive automotive applications.
The devices are qualified according to AEC-Q100 standards and feature an environmentally friendly, lead-free and RoHS-compliant bill of materials.
