8.3.3.4.2 PP_CABLE Input Good Monitor

The TPS65988DJ monitors the voltage at the PP_CABLE pins prior to enabling the power switch. If the voltage at PP_CABLE exceeds the input good threshold the switch is allowed to close, otherwise the switch remains open. Once the switch has been enabled, PP_CABLE is allowed to fall below the input good threshold.
