Digital-output magnetic sensor (Hall IC) block diagram

The digital-output magnetic sensor is essentially a sensor which detects the magnetic flux density of a magnet and gives a digital signal at the output. The digital-output magnetic sensor is thus suitable for detecting the position of a magnet which is useful for open/close switch functions and slider functions in mobile phones, notebook PC, digital camera and digital video camera, etc. This application note will introduce the basic application circuit of the digital-output magnetic sensor and what to take note of during normal operation. We hope that you will find it useful.
