Product Description
Allegro Microsystems A3212ELHLT-T is a surface mount Hall Effect sensor designed for precise and low-power magnetic field detection within a voltage range of 2.5 V to 3.5 V. Its small, compact SOT-23 3-pin package dimensions (2.98 mm length, 1.91 mm width, 950 μm height) make it suitable for space-constrained industrial and automotive applications.
This sensor employs chopper stabilised CMOS technology to significantly reduce residual offset voltages caused by temperature variations or mechanical stress. The omnipolar magnetic sensing capability allows it to detect both north and south poles interchangeably, providing a latched digital output signal.
The A3212ELHLT-T features a fast response time of 45 microseconds ensuring timely detection of magnetic field changes. Its supply current is low at 2 mA, allowing for efficient power usage in battery-powered and embedded systems. The device complies with the rigorous AEC-Q100 automotive standard, guaranteeing high reliability and performance in automotive environments.
Typical applications include position sensing, speed detection, current sensing, and proximity sensing in automotive and industrial control systems. The SOT-23 surface mount package facilitates easy integration onto printed circuit boards.
