A1120LUA-T Description

Short technical summary and product information.

The Allegro Microsystems A1120LUA-T is a Hall-effect unipolar switch IC. It is designed for high temperature stability and resistance to physical stress, making it suitable for operation in demanding environments up to 150°C.

 

Key electrical characteristics include a supply voltage range of 3V to 24V and an open-drain output capable of sinking up to 25 mA. The device utilizes Hall effect technology and operates as a unipolar switch, activated by a south pole magnetic field. It has a typical trip point of 5mT and a release point of 0.5mT.

 

This sensor IC is housed in a 3-pin SIP package and is designed for through-hole mounting. Its robust design includes features like dynamic offset cancellation for superior high-temperature performance and output short-circuit protection. The device is also qualified for automotive applications (AEC-Q100).

 

Applications for this sensor include systems requiring magnetic field detection and switching, such as position sensing, speed detection, and lid/door closure detection in automotive and industrial settings.
