The ATS344 device is a high precision, back-biased programmable Hall effect linear sensor integrated circuits (IC) with a configurable current mode pulse width modulated output, for both automotive and non-automotive applications. The signal path of the ATS344 provides flexibility through external programming that allows the generation of an accurate, and customized output response from a ferro-magnetic target perturbation. The ATS344 incorporates a 2-wire 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 lead-frame plated 3-pin SP package.
The ATS344 is ideally suited to the following markets & applications:
