When the logic pins are set to a channel under a fault, the overvoltage detection will trigger, the switch will open, and the drain pin will operate as described in Section 8.3.2.4. During such an event, all other channels not under a fault can continue to operate as normal. For example, if S1A voltage exceeds V_DD, and the logic pins are set to S1A, and the DR pin is set to logic low, then the drain output is pulled to V_DD. Afterwards if the logic pins are changed to set S1B, which is not in overvoltage or undervoltage, then the drain will disconnect from the pullup to V_DD and the S1B switch will be enabled and connected to the drain, operating as normal, although there is still an overvoltage condition present on S1A. If the logic pins are switched back to S1A, then the S1B switch will be disabled, the drain pin will be pulled up to V_DD again, and the switch from S1A to drain will be disabled until the overvoltage fault is removed.
