Hall Sensor Interface
The Hall sensor interface is used for the BLDC sensor based motor control application. The Hall sensors
are used to determine the actual motor rotor sector.
The on-board interface provides the 5V 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 7
. A
single pole RC low-pass filter is present to reduce the signal noise.
For a detailed JP600 connector signal description, see
