MicroSystemsThe Allegro MicroSystems ALS31313KLEATR-2000 is an automotive 3D linear Hall effect sensor that has board mount Hall effect/magnetic sensors. This sensor is designed to measure the rotational speed, angular position, and current in motor control applications. It is integrated with a low-power, low-noise Hall sensing element, an analog-to-digital converter, temperature compensation, and signal conditioning circuitry. It features high accuracy and linearity as well as a wide power supply range (2.4V to 18V), a low quiescent current requirement (8 µA), and a wide operating temperature range from -40°C to +135°C. Other features include a programmable hysteresis, adjustable current output, and an adjustable current limit. This sensor is ideal for use in automotive applications including ABS, vehicle speed sensing, and motor control.
