5.1.16 TP14 (PA and PB): VBUS Test Point
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.
