The A3214 is a micropower, ultra-sensitive, pole-independent Hall-effect switch with a latched digital output, designed for battery-operated applications requiring low power consumption. It operates from 2.4 to 5.5 V and consumes 14 µA average current at 2.75 V. The A3214EUA-T variant uses a 3-pin SIP through-hole package (suffix UA) rated for operation from -40°C to 85°C and is lead-free with matte-tin-plated leads. It is AEC-Q100 automotive qualified and features chopper stabilization for temperature stability and minimal switch point drift. The device can handle up to 1 mA output current and is suited for replacing reed switches due to solid-state reliability and ease of assembly.
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.
