Micropower Hall-Effect Switches

Extend the life of your battery-powered devices with these integrated Hall-effect sensor ICs. These switches offer low power consumption and are ideal for use in on/off switching applications and for detecting tampering in utility meters. Current consumption is significantly reduced by cycling the awake and sleep periods.

Allegro offers unique 3D omnipolar sensor ICs that can detect magnetic fields of either polarity and in any direction. They are highly sensitive, making them ideal for detecting tampering via magnetic fields in applications such as smart meters, ATMs, gambling/gaming machines, ticket machines and electronic locks.
