APS12625

and APS12626

2D Hall-Effect

Speed and Direction Sensor ICs

DESCRIPTION

The APS12625 and APS12626 integrated circuits are dual

ultrasensitive Hall-effect latches optimized for use with ring

magnets. They feature both vertical and planar Hall elements

with sensing axes that are orthogonal to one another, providing

90° of phase separation. This phase separation is inherently

independent of magnet pole spacing and air gap. No target

optimization is required, making them extremely flexible and

easy to use.

For example, the ring magnet pole-pitch can be changed without

having to modify the sensor position or other mechanical design

details. Additionally, XY, ZX, and ZY options are available to

work in almost any orientation to the target. The APS12625

features Speed and Direction outputs, while the APS12626 has

quadrature outputs (Channel A/B).

A unique feature allows the host system to restore the correct

state after power-cycling the device (-P option). This reduces

the potential accumulation of lost counts/pulses when the device

wakes up with one or more sensors in its hysteresis region.
