Configuration ID 0: Docking System
Table 3. Configuration ID 0
5.3.3.1.1
Overview
The TPS65982-EVM will power-on and initialize into configuration ID 0 when all 4 of the DIP switches
[B0:B3] on switch bank S1 are pushed to the left-hand side. Configuration ID 0 is designed to model a
docking system application.
A TPS65982-EVM configured as a dock is capable of providing (sourcing) 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.
5.3.3.1.2
Source Capabilities
This configuration is capable of negotiating PD contracts to source 5 V at 3 A, 12 V at 3 A through the
PP_HV internal FET path, and 20 V at 5 A through the PP_EXT external FET path.
5.3.3.1.3
Sink Capabilities
This configuration is capable of negotiating PD contracts to sink 5 V at 0 A.
5.3.3.1.4
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).
5.3.3.1.5
Ideal Connections
This configuration pairs ideally with a TPS65982-EVM using configuration ID 3 for providing power and
entering DisplayPort alternate mode. This configuration is also compatible with a TPS65982-EVM using
configuration ID 1 for providing power and entering DisplayPort alternate mode. These TPS65982-EVM
configurations respectively emulate notebook, tablet, and charger-adapter applications and the same
performance is expected when connected to actual applications of these products.
