(1) The V_CC pin is not a pin on the DRV870xD-Q1, but a V_CC supply voltage pullup is required for open-drain outputs nFAULT. These pins
can be pulled up to either AVDD or DVDD.
(2) The R_(VDRAIN) resistor should be used between the VDRAIN and VM pins to minimize current to the VDRAIN pin if no external reserve
battery protection is implemented on the VDRAIN pin.
