A3214ELHLT-T Description

Short technical summary and product information.

The Allegro Microsystems A3214ELHLT-T is an ultra-sensitive, pole-independent Hall-effect switch designed for battery-operated, hand-held equipment. It features a latched digital output and operates with either a north or south pole of sufficient strength.

 

This device supports a wide operating voltage range of 2.4V to 5.5V, with a typical average operating power of 14 µW at 2.75V. It is chopper stabilized for improved stability and reduced offset voltage. The switch has a sensing range of ±7mT Trip and ±1mT Release.

 

The A3214ELHLT-T is housed in a SOT-23W surface-mount package. Its polarity independence and minimal power requirements make it suitable for replacing reed switches, offering superior reliability and ease of manufacturing.

 

Key specifications include an operating temperature range of -40°C to 85°C and an output type of Open Drain. The Hall Effect technology ensures solid-state reliability.
