Product Overview

The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for applications requiring precise speed and direction sensing, particularly with ring magnets. These ICs feature integrated vertical and planar Hall elements, providing 2D magnetic sensing capabilities with inherent 90 phase separation, independent of magnet pole spacing and air gap. This eliminates the need for target optimization, offering significant design flexibility. The APS12625 provides Speed and Direction outputs, while the APS12626 offers individual Quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) helps prevent lost counts/pulses. These devices are ideal for automotive and industrial motor/encoder applications, including power steering, seat/window/sunroof motors, trunk/door actuators, and white goods.
