Allegro (A1120LLHLT-T) Hall Effect Sensor, Unipolar, 25 mA, SOT-23, 3 Pins

Hall Effect Sensor, Unipolar, 25 mA, SOT-23, 3 Pins, 3 V, 24 V\ Product Overview The A1120LLHLT-T is a chopper-stabilized unipolar Precision Hall Effect Switch has extremely temperature-stable and stress-resistant features. Device includes on a single silicon chip a voltage regulator, hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger and a short- circuit protected open-drain output to sink up to 25mA. A south pole of sufficient strength turns the output ON. Removal of the magnetic field turns the output OFF. It is specially suited for operation over extended temperature ranges to 150°C. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-moulding, temperature dependencies and thermal stress. Resistant to physical stress Superior temperature stability Output short-circuit protection Operation from unregulated supply Reverse-battery protection Solid-state reliability AEC-Q100 Automotive qualified Applications Sensing & Instrumentation, Automotive Product Information Hall Effect Type: Unipolar Output Current: 25mA Sensor Case Style: SOT-23 No. of Pins: 3Pins Supply Voltage Min: 3V Supply Voltage Max: 24V Operating Temperature Min: -40°C Operating Temperature Max: 150°C
