7.4.1 Bridge Control
Two control modes are available in the DRV8835: IN/IN mode, and PHASE/ENABLE mode. IN/IN mode is
selected if the MODE pin is driven low or left unconnected; PHASE/ENABLE mode is selected if the MODE pin is
driven to logic high. Table 3 and Table 4 show the logic for these modes.

7.4.2 Sleep Mode
If the VCC pin reaches 0 V, the DRV8835 enters a low-power sleep mode. In this state all unnecessary internal
circuitry powers down. For minimum supply current, all inputs should be low (0 V) during sleep mode.
