Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer 2D magnetic sensing 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, allowing for flexible mechanical design. 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) prevents lost counts/pulses. They are automotive grade, qualified per AEC-Q100 up to 175C junction temperature, and operate from 2.8 to 5.5 V.
