Allegro MicroSystems Micropower Ultra-Sensitive Hall-Effect Switch, Part #A3214ELHLT-T | Sensor | DEX

Allegro MicroSystems Micropower Ultra-Sensitive Hall-Effect Switch, Part #A3214ELHLT-T | Sensor | DEX features: • AEC-Q100 automotive qualified • Micropower operation • Operate with north or south pole • 2.4 to 5.5 V battery operation • Chopper stabilized □ Superior temperature stability □ Extremely low switchpoint drift □ Insensitive to physical stress • High ESD protection • Solid-state reliability • Small size • Easily assembly into applications due to magnetic pole independence The A3213 and A3214 integrated circuits are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output. They are especially suited for operation in battery-operated, hand-held equipment such as cell and cordless telephones and palmtop computers. A 2.4 to 5.5 V operation and a unique clocking scheme reduce the average operating power requirements: the A3213 to 825 µW, the A3214 to 14 µW (typical, at 2.75 V). Except for operating duty cycle and average operating current, the A3213 and
