Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They feature vertical and planar Hall elements with orthogonal sensing axes, providing inherent 90 phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, offering high flexibility. 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 accumulation of lost counts/pulses. These devices are automotive grade, qualified per AEC-Q100 with high junction temperature operation and output short-circuit protection.
