The TPS65988EVM is capable of requesting a power role swap when the barrel jack is connected on an EVM that is currently bus-powered. The barrel jack voltage is sensed by a comparator, which drives GPIO1 (BJ_DETECT) on the TPS65988. By default, the Barrel Jack Detect is not enabled. To enable Barrel Jack Detect place R109 and refer to the TPS65988 Utilities Tool User Guide and TPS65988 Firmware User Guide. Figure 5-19 highlights these features.
