The A3213ELHLT-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 309 µA average current at 25°C. The device is packaged in a 3-pin SOT23W surface-mount package (suffix LH) and is AEC-Q100 automotive qualified. It is rated for operation from -40°C to 85°C and features chopper stabilization for temperature stability and low offset drift. The output is a MOSFET with 1 mA sourcing capability and supports high ESD protection.
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.
