5.3.3.3 Configuration ID 2: Notebook (or Mobile Workstation) with Thunderbolt Mode Capabilities
Table 5. Configuration ID 2
5.3.3.3.1 Overview
The TPS65982-EVM will power-on and initialize into configuration ID 2 when the 1
st
, 3
rd
, and 4
th
DIP
switches [B0],[B2], [B3] on switch bank S1 are pushed to the left-hand side and the 2
nd
DIP switch [B1] on
switch bank S1 is pushed to the right-hand side. Configuration ID 2 is designed to model a Thunderbolt
notebook (or mobile workstation) application.
A TPS65982-EVM configured as a notebook is capable of providing (sourcing) power or consuming
(sinking) power. A fully-featured Type-C port on a notebook can be capable as a downstream-facing port
(DFP) for DisplayPort video and Thunderbolt Alternate Mode video+data, which is also emulated by this
EVM configuration. This configuration will also initiate a PD power role swap to sink and/or a PD data role
swap to DFP.
5.3.3.3.2 Source Capabilities
This configuration is capable of negotiating PD contracts to source 5 V at 3 A through the PP_5V0 internal
FET path and 12 V at 3 A through the PP_HV internal FET path.
5.3.3.3.3 Sink Capabilities
This configuration is capable of negotiating PD contracts to sink 5 V at 0 A and 20 V at 3 A through the
PP_EXT external FET path.
5.3.3.3.4 Video Capabilities
This configuration is capable of negotiating a USB PD Thunderbolt Alternate Mode contract for video+data
as a downstream-facing port (DFP). This configuration is also capable of negotiating a USB PD alternate
mode contract for DisplayPort video as a downstream-facing port (DFP). An alternate mode contract will
only be negotiated successfully when connected to a product which is capable of Thunderbolt Alternate
Mode or DisplayPort video as an upstream-facing port (UFP).
5.3.3.3.5 Ideal Connections
This configuration pairs ideally with a TPS65982-EVM using configuration ID 5 for consuming or providing
power and entering Thunderbolt Alternate Mode. This configuration is also compatible with a TPS65982-
EVM using configuration ID 4 for providing power and entering DisplayPort alternate mode. To test this
configuration as a power consumer which enters USB2.0 and 3.1 for data, pair it with a TPS65982-EVM
using configuration ID 6. These TPS65982-EVM configurations respectively emulate dock, dongle, and
charger-adapter applications and the same performance is expected when connected to actual
applications of these products.
