The A3214ELHLX-T is a micropower, ultra-sensitive, pole-independent Hall-effect switch with a latched digital output, designed for battery-operated handheld devices. It operates from 2.4 to 5.5 V and consumes 6 µA typical average current at 2.75 V. The device is housed in a 3-pin SOT23W surface-mount package (suffix LH) and is rated for operation from -40°C to 85°C. It is AEC-Q100 automotive qualified and compatible with lead-free assembly. The output is activated by either a north or south magnetic pole and remains off in the absence of a field, eliminating the need for signal conditioning.
The A3213/4 Hall-effect switches offer ultrasensitive and reliable performance with latched digital output and an extended temperature range (-40°C to 150°C), making them suitable for demanding applications. Pole-independent operation simplifies design.
