A1220ELHLT-T Description

Short technical summary and product information.

The Allegro Microsystems A1220ELHLT-T is a Hall-effect latch sensor designed for reliable operation over extended temperature ranges. This device is built on a single silicon chip and includes a voltage regulator, Hall-voltage generator, amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output capable of sinking up to 25 mA.

 

Key electrical specifications include an operating voltage range of 3V to 24V and a current draw of 4mA. The sensor utilizes Hall Effect technology and functions as a latch, requiring a sufficient south pole strength to turn on and a north pole to turn off. It offers a sensing range of 4mT trip and -4mT release.

 

The device is housed in a SOT-23W surface-mount package, making it suitable for various applications. The operating temperature range is specified as -40°C to 85°C (TA), with an extended range to 150°C available in other variants. Its robust design provides resistance to physical stress and superior temperature stability, making it ideal for automotive and industrial applications.
