A1101EUA-T Hall Effect Switch

The A1101EUA Hall-effect, unipolar switches are extremely temperature-stable and stress-resistant sensor ICs.

Each device includes on a single silicon chip a voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator permits operation from 3.8 to 24 V. The extensive on-board protection circuitry makes possible a ±30 V absolute maximum voltage rating for superior protection in automotive and industrial motor commutation applications, without adding external components.

A south pole of sufficient strength turns the output on. Removal of the magnetic field turns the output off.

Features
