New 2D Hall-effect speed and direction sensor ICs for motor and magnetic encoder applications

Allegro MicroSystems Europe has released a new family of 2D Hall-Effect Latch ICs featuring both planar and vertical Hall elements. The APS12625 and APS12626 sensor ICs offer reduced system size and BOM cost along with an increase in performance and flexibility due to 2D sensing. They meet ISO 26262 and are qualified per AEC-Q100, making them ideal for automotive and other safety systems. The APS12625 features direction and speed outputs where the APS12626 has quadrature (Channel A and B) outputs. A unique feature, which is optional, allows the host system to restore the prior state of the sensor after a power-cycle. This decreases the potential accumulation of lost counts in intelligent motion applications such as window lifts with anti-pinch requirements. “Allegro’s vertical Hall technology enables sensor ICs that are uniquely suited to magnetic motor/encoder applications,” explained Jim Judkins, product line director for Digital Position Sensor ICs at Allegro MicroSystems. Jim continued to explain that, “Designers can achieve lower BOM cost and power in less board area while meeting their safety goals and spending less time iterating designs to support changes in magnet pitch or system form-factor.”
