Part number : AH44E
Functions : Hall Effect Sensor
Manufacturer : Allegro
Package information : TO-92UA Type
The sensor IC used is AH44E unipolar digital Hall Effect sensor by allegro. The AH44E is a small, versatile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry features low noise output, which makes it unnecessary to use external filtering. It also includes precision resistors to provide increased temperature stability and accuracy. The operating temper ature
range of these linear Hall sensors is -40oC to 85oC, appropriate for commercial, consumer and industrial applications. The sensor has three pins pin1-Vcc, pin2-GND, and pin3-Output.
