The VBUS test points are used to measure VBUS at each USB Type-C port A/B connector. With PD power possibly going up to 20 V, use caution when connecting and disconnecting probes on the TPS65988EVM. The VBUS test point is capable of drawing up to 3 A for an external load. Note that a PD power contract with the necessary capability must be negotiated in order to draw current from the VBUS test point. Refer to the TPS65988 Configuration Tool User Guide for configuration instructions. Figure 5-33 and Figure 5-34 highlights these features.
