APS12625 and APS12626 2D Hall-Effect Speed and Direction Sensor ICs
■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.
