Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer flexible 2D magnetic sensing with orthogonal vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, making them easy to integrate. The APS12625 provides Speed and Direction outputs, while the APS12626 offers quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) prevents lost counts/pulses. These devices are automotive grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V with high junction temperature capability.
