Overview 44e hall sensor
Allegro’s AH44E unipolar digital Hall effect sensor is the IC used in this application. This linear Hall-effect gadget, which may be driven by either a permanent or an electromagnet’s magnetic field, is tiny and adaptable. An inductor uses a magnetic field to produce an output voltage that is proportional to that of the input voltage. Because of the low noise output of the integrated circuitry, extra filtering is not necessary. Temperature stability and accuracy are further improved by using precision resistors. These linear Hall sensors have a temperature range of -40oC to 85oC, which is suitable for commercial, consumer, and industrial use. Pin1 is Vcc, pin2 is GND, and pin3 is output on the sensor.
Specifications of 44e hall sensor :
