Concept: 3144 series Hall switch integrated circuit applies the Hall effect principle and uses semiconductor integrated technology to fabricate a magnetic sensitive circuit. It is a magnetic sensing circuit composed of a voltage regulator, a Hall voltage generator, a differential amplifier, a Schmidt trigger, a temperature compensation circuit, and an output stage with an open collector. Its input is the magnetic induction intensity, and the output is a digital voltage signal.

Advantages: small size, high sensitivity, fast response speed, good temperature performance, high precision and high reliability

Typical applications: no touchpoint switch, automotive igniter, brake circuit, position, speed detection and control, safety alarm device,Textile control system
