Allegro adds magnet to back-biased differential linear Hall sensor IC
Differential Hall elements are integrated in the ATS344 high precision, back-biased, programmable Hall-effect sensor IC. Allegro MicroSystems Europe offers the ATS344 packaged in a custom back-biased package that includes an integrated magnet.
The IC incorporates a two-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 suitable for automotive applications requiring high resolution detection of long stroke (above 5.0mm) linear motion.
The integrated back-bias magnet simplifies packaging for the customer, explains Allegro. It requires only a ferrous target to detect. The ATS344 is offered in a Pb free, 100% matt-tin leadframe plated three-pin SP package.
