Setup
5.3.3.12 Configuration ID 11: Mini-Docking System
Table 14. Configuration ID 11
5.3.3.12.1 Overview
The TPS65982-EVM will power-on and initialize into configuration ID 11 when [B0], [B1] and [B3] on
switch bank S1 are pushed to the right-hand side and [B2] is pushed to the left. Configuration ID 11 is
designed to model a docking system application.
A TPS65982-EVM configured as a dock is capable of providing (sourcing) power and consuming (sinking)
power. The fully-featured Type-C port of a dock which faces a laptop can be an upstream-facing port
(UFP) for DisplayPort video, which is also emulated by this EVM configuration. This configuration will also
initiate a PD power role swap to source and/or a PD data role swap to UFP.
5.3.3.12.2 Source Capabilities
This configuration is capable of negotiating PD contracts to source 5 V at 3 A, and 20 V at 3 A through the
PP_EXT external FET path.
5.3.3.12.3 Sink Capabilities
This configuration is capable of negotiating PD contracts to sink 5 V at 1.5 A and 20 V at 3 A
5.3.3.12.4 Video Capabilities
This configuration is capable of negotiating a USB PD alternate mode contract for DisplayPort video as an
upstream-facing port (UFP). An alternate mode contract will only be negotiated successfully when
connected to a product which is capable of DisplayPort video as a downstream-facing port (DFP).
5.3.3.12.5 Ideal Connections
This configuration pairs ideally with a TPS65982-EVM using configuration ID 1 for consuming or providing
power and entering DisplayPort alternate mode. When acting as a bus-powered dock connecting to
configuration ID 3 will power the dock from bus-power and will negotiate DisplayPort alternate mode.
