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

PublishTime：2021-07-14

●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 oflost counts/pulses when the device wakes up with one or more sensors in its hysteresis region.
●On a single silicon chip, these devices include: three Hall plates (one planar and two vertical), a multiplexer, a small-signal amplifier, chopper stabilization, a Sclimitt trigger, and two NMOS output transistors which can sink up to 10 mA continuously. They operate from a regulated supply voltage of 2.8 to 5.5 V and have been qualified beyond the requirements of AEC-Q100 grade 0 for operation up to 175°C junction temperature.
●The small geometries of the BiCMOS process allow these devices to be offered in an ultrasmall package. Package designator “LH" indicates a modified SOT23-W surface-mount package. This package is RoHS compliant and lead (Pb) free, with 100% matte tin leadframe plating.
