3.9 Hall Sensor Interface
The Hall sensor interface is used for BLDC sensor based motor control applications. The Hall sensors are used to determine
the actual motor rotor sector.
The on-board interface provides the 5 V power supply voltage to supply the sensors. The Hall interface inputs are designed to
support an open collector as well as push-pull Hall sensors outputs (see Figure below). A single pole RC low pass filter is
present to reduce a signal noise.
