Introduction

The AEW632 high-sensitivity latching digital Hall-effect sensor IC is a compact, versatile device driven by the magnetic field of permanent or electromagnets. The device is designed to respond to alternating north and south poles. The AEW632 is turned on by the south pole.

The AEW632 features a typical high magnetic sensitivity of 30 Gs, providing reliable switching points. Compared to competing high-sensitivity Hall-effect latching sensor ICs that use chopper stabilization, this product does not employ chopper stabilization on the Hall element, delivering a clean output signal and faster latching response time.

For brushless DC motor manufacturers requiring latching sensors with reliable, consistent performance, the AEW632 accepts any DC supply voltage from 2.3 Vdc to 33 Vdc. Thanks to the high sensitivity of the indium antimonide Hall element, the AEW632 offers excellent switching point symmetry and consistent repeatability, along with faster response time to magnetic field variations, thereby improving motor efficiency.
