Drive type Hall chips are commonly used in brushless motors, which can reflect mechanical events in a magnetic drive manner. In static state (without magnetic field), theoretically, the output should be equal to half of the power supply voltage within the operating voltage and temperature range. Increasing the South Pole magnetic field will increase the voltage from its static voltage. Conversely, increasing the North Pole magnetic field will increase the voltage from its static voltage. These components measure the angle, proximity, motion, and magnetic flux of the current.
