The Allegro Microsystems A3213ELHLT-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 across a wide voltage range of 2.4V to 5.5V.
This device is especially suited for applications requiring minimal power consumption, with typical average operating power as low as 825 µW for the A3213 and 14 µW for the A3214 at 2.75V. Its polarity independence allows it to replace reed switches, offering superior reliability and ease of manufacturing.
The A3213ELHLT-T utilizes chopper stabilization for improved stability and reduced offset voltage. It is supplied in a compact SOT-23W surface-mount package, facilitating easy assembly into various applications. The operating temperature range is -40°C to 85°C.
Key electrical characteristics include an open-drain output type and a sensing range of ±7mT Trip, ±1mT Release. The device functions as an omnipolar switch, responding to either a north or south pole of sufficient strength.
