ZHCSHZ0A April 2018 – July 2018 DRV8306
PRODUCTION DATA.
Some motors use digital Hall sensors with open-drain outputs. These sensors can also be used with the DRV8306 device, with the addition of a few resistors as shown in Figure 27.
The negative (HNx) inputs are biased to DVDD / 2 by a pair of resistors between the DVDD pin and ground. For open-collector Hall sensors, an additional pullup resistor to the VREG pin is required on the positive (HPx) input. Again, the DVDD output can usually be used to supply power to the Hall sensors.
