New Back-Biased Differential Linear Hall Sensor IC

Allegro MicroSystems, LLC introduces 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 2wire current mode PWM output in order to help minimize 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 (>5mm) 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% matte-tin leadframe plated 3-pin SP package. Allegro’s ATS344 is priced at $3.825 in quantities of 1,000.
