Allegro Microsystems Surface Hall Effect Sensor Digital Omnipolar 3 V to 24 V SOT-23 3-Pin A1126LLHLT-T

Allegro Microsystems A1126LLHLT-T is an advanced omnipolar surface Hall effect sensor switch designed for detecting magnetic fields with high sensitivity and accuracy.

The device features a digital output and is built in a SOT-23 3-pin surface mount package, measuring just 2.98 mm in length, 1.91 mm in width, and 950 μm in height, making it suitable for compact PCB layouts.

This sensor integrates a voltage regulator that permits operation across a wide supply voltage range from 3 V to 24 V, accommodating varied system requirements.

With a low supply current of 4 mA and a fast response time of 25 microseconds, it is ideal for applications demanding efficient power consumption and rapid magnetic field detection.

The A1126LLHLT-T sensor employs chopper stabilization technology, ensuring low switch point drift, superior temperature stability, and immunity to physical stress and electromagnetic interference.

Its omnipolar operation allows activation by either north or south magnetic polarities without requiring magnet orientation, effectively replacing reed switches in many applications.

Certified to automotive AEC-Q100 standards and RoHS compliant, the sensor can operate reliably within extended ambient temperature ranges from -40°C to 150°C. The output stage is an open-drain configuration with built-in short-circuit protection, providing robust system integration and protection.

This sensor is highly suitable for industrial, automotive, consumer electronics, and manufacturing applications requiring precise and reliable magnetic field sensing, such as position sensing, speed detection, and current sensing.
