Setup
5.3.3.8
Configuration ID 7: High-Power Bus-Powered Device
Table 10. Configuration ID 7
5.3.3.8.1
Overview
The TPS65982-EVM will boot up and initialize into configuration ID 7 when [B0], [B1], and [B2] of the DIP
switches on switch bank S1 are pushed to the right-hand side and [B3] is pushed to the left. Configuration
ID 7 is designed to model a high-power bus-powered device application.
A TPS65982-EVM configured as a high-power bus-powered device is capable of consuming (sinking)
power only. A fully-featured Type-C port on a high-power bus-powered device can be capable of USB 2.0
and USB3.1 data, which is also emulated by this EVM configuration.
5.3.3.8.2
Source Capabilities
This configuration is designed to be a consumer (sink) of power only, and therefore does not have any
source capabilities.
5.3.3.8.3
Sink Capabilities
This configuration is capable of negotiating PD contracts to sink 5 V at 3 A, 12 V at 3 A, 20 V at 5 A
through the PP_EXT external FET path.
5.3.3.8.4
Video Capabilities
This configuration is capable of USB 2.0 and USB 3.1 data only, and therefore does not have any video
capabilities.
5.3.3.8.5
Ideal Connections
This configuration pairs ideally with a TPS65982-EVM using configuration ID 6 for consuming power and
enters USB2.0 and 3.1 mode for data by default. This configuration is also compatible with a TPS65982-
EVM using configuration ID 0 or 5 for consuming power and entering USB2.0 and 3.1 mode for data by
default. This configuration is also compatible with a TPS65982-EVM using configuration ID 2 or 3 for
consuming power and entering USB2.0 and 3.1 mode for data by default. These TPS65982-EVM
configurations respectively emulate charger-adapter, dock, and notebook applications and the same
performance is expected when connected to actual applications of these products.
