Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. Featuring integrated vertical and planar Hall elements with orthogonal sensing axes, they provide 90 phase separation independent of magnet pole spacing and air gap, eliminating the need for target optimization. The APS12625 offers Speed and Direction outputs, while the APS12626 provides 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.
