New back-biased differential linear Hall sensor IC from Allegro

News

Allegro MicroSystems Europe has introduced a new high-precision, back-biased, programmable Hall-effect sensor IC. Allegro’s ATS344 includes differential Hall elements and is packaged in a custom back-biased package that includes an integrated magnet.

This new device incorporates a 2-wire current mode PWM output in order to help minimise pin count for remote sensors. It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters. The ATS344 is ideal for automotive applications requiring high resolution detection of long stroke (> 5 mm) linear motion.

The integrated back-bias magnet greatly simplifies packaging for the customer, requiring only a ferrous target to detect. The ATS344 is offered in a Pb free, 100% matt-tin lead frame plated 3-pin SP package.
