8.1.1.1 Typical Configuration

The Hall sensor inputs on the DRV8306 device can interface with a variety of Hall sensors. Typically, a Hall element is used, which outputs a differential signal on the order of 100 mV. To use this type of sensor, the DVDD regulator can be used to power the Hall sensor. Figure 26 shows the connections.

Because the amplitude of the Hall-sensor output signal is very low, capacitors are often placed across the Hall inputs to help reject noise coupled from the motor. Capacitors with a value of 1 nF to 100 nF are typically used.
