Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They offer 2D magnetic sensing capabilities with vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, ensuring flexibility and ease of use. The devices feature options for various orientations (XY, ZX, ZY) and offer either Speed and Direction outputs (APS12625) or quadrature outputs (APS12626). A unique power-cycling restore feature (-P option) minimizes lost counts/pulses. These automotive-grade ICs operate from 2.8 to 5.5 V and are qualified per AEC-Q100 for operation up to 175C junction temperature.
