Setup
5.3.2.2
Consumer or Provider (CONS or PRVDR) Event
After a plug event has occurred and cable orientation detection is complete, a USB PD contract will be
negotiated. When a USB PD contract has been successfully negotiated, this event will occur and either
LED D7 (
CONS
) or LED D6 (
PVDR
) will turn ON to indicate that the TPS65982-EVM is acting as a power
consumer (
CONS
ON and
PVDR
OFF) or power provider (
PVDR
ON and
CONS
OFF).
5.3.2.3
USB PD Voltage (5V, HV, or Blinking HV) Event
After a plug event has occurred, cable orientation detection is complete, and a USB PD contract has been
negotiated, a voltage will be present on VBUS (TP3) at the USB Type-C port (J1). When VBUS is present,
this event will occur and one of the following LED indicators may be ON or blinking ON or OFF: LED D8
(
5V
) or LED D9 (
HV
). If the TPS65982 is acting as a power provider and the voltage on VBUS is 5 V, LED
D8 (
5V
) will be ON. If the TPS65982 is acting as a power provider and the voltage on VBUS is 12 V, LED
D9 (
HV
) will be ON. If the TPS65982 is acting as a power consumer or provider and the voltage on VBUS
is 20 V, LED D9 (
HV
) will be blinking ON and OFF.
5.3.2.4
DisplayPort Alternate Mode (LED A) Event
When a USB PD contract has been negotiated to enter an alternate mode for DisplayPort video, LED A
(D4) will blink ON and OFF every 1 second to indicate that 2-lane DisplayPort alternate mode has been
entered, and if LED A (D4) remains solid then 4 lane DisplayPort alternate mode has been entered.
5.3.2.5
Thunderbolt Alternate Mode (LED B) Event
When a USB PD contract has been negotiated to enter an alternate mode for Thunderbolt video+data,
LED B (D5) will blink On and OFF every 1 second to indicate that this event has occurred.
