The A3214LUA-T is a micropower, pole-independent Hall-effect switch with a latched digital output, designed for battery-operated applications such as portable electronics. It operates from 2.4 V to 5.5 V and consumes 6 µA typical average current at 2.75 V. The device is housed in a 3-pin SIP through-hole package (suffix UA) with a matrix HD style, rated for ambient temperatures from -40°C to 150°C. It is AEC-Q100 automotive qualified and features a chopper-stabilized design for temperature stability and low power operation. The output is a MOSFET with 1 mA sourcing capability and supports high ESD protection. The package is lead-free with matte-tin plating.
