The A3213EUA-T is a micropower, pole-independent Hall-effect switch with a latched digital output, designed for battery-operated applications requiring low power consumption and high reliability. It operates from 2.4 to 5.5 V and consumes 309 µA average operating current at 25°C. The device is housed in a 3-pin SIP through-hole package (suffix UA) and is rated for an ambient temperature range of -40°C to 85°C. It features chopper stabilization for reduced temperature drift and magnetic pole independence, eliminating the need for signal conditioning. The part is AEC-Q100 automotive qualified and includes a MOSFET output for direct drive capability. The chopper-style UA package is designated as not for new design; the matrix HD style UA package is recommended instead.
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.
