A1203LLHLT-T Description

Short technical summary and product information.

The Allegro A1203LLHLT-T is a Hall-effect bipolar switch from the A120x family, built with BiCMOS technology. It offers continuous-time operation with fast power-on time and low-noise performance. The device integrates a voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor on a single silicon chip.

 

Key electrical specifications include an operating voltage range of 3.8V to 24V and a current draw of 7.5mA. The switch features a sensing range of ±9.5mT for both trip and release points. It is designed for applications requiring stable operation over a wide temperature range, from -40°C to 150°C.

 

The A1203LLHLT-T is available in an SOT-23W package, a miniature low-profile surface-mount solution. The package is lead-free with 100% matte-tin-plated leadframes. The device also includes on-board protection circuitry, providing a ±30V absolute maximum voltage rating suitable for automotive environments without external components. It is AEC-Q100 automotive qualified.
