A1203EUA-T Description

Short technical summary and product information.

The Allegro A1203EUA-T is a Hall-effect bipolar switch from Allegro Microsystems, built with BiCMOS technology for continuous-time operation, fast power-on time, and low-noise performance. This device integrates a voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and an NMOS output transistor on a single silicon chip.

 

It operates from 3.8V to 24V and features extensive on-board protection circuitry, allowing for a ±30V absolute maximum voltage rating suitable for automotive and motor commutation applications. The A1203EUA-T offers a sensing range of ±9.5mT and an open-drain output type. It is designed for stable operation across its specified temperature range of -40°C to 85°C.

 

This component is available in a 3-pin SIP (Single In-line Package) for through-hole mounting. The package is lead-free with 100% matte-tin-plated leadframes, contributing to its solid-state reliability and robust EMC performance.
