Micropower Hall-Effect Switches

Extend the life of your battery-powered devices with our integrated Hall-effect sensor ICs. These switches offer low power consumption. They are ideal for use in on/off switching applications and for detection of tampering in utility meters. Using these switches, you may be able to reduce your current consumption significantly by cycling the awake and sleep periods.

We offer unique 3D omnipolar sensor ICs that can detect magnetic fields of either polarity and in any direction. The high sensitivity of these ICs makes them ideal for detecting tampering via magnetic fields in applications such as smart meters, ATMs, gambling/gaming machines, ticket machines, and electronic locks.
