7.3.11 VDS Pin (DRV8702D-Q1 Only)

The VDS pin on the DRV8702D-Q1 device is used to select the VDS threshold voltage for overcurrent detection.

Tying the VDS pin to ground selects the lowest setting of 0.06 V. Leaving this pin open selects the setting of
0.48 V. Tying the VDS pin to the AVDD the pin disables the VDS monitor. For a detailed list of VDS configurations, see Table 7.
