5.3.3.5 Configuration ID 4: Dongle
Table 7. Configuration ID 4
5.3.3.5.1 Overview
The TPS65982-EVM will boot up and initialize into configuration ID 4 when the 1
st
, 2
nd
, and 4
th
DIP
switches [B0], [B1], and [B3] on switch bank S1 are pushed to the left-hand side and the 3
rd
DIP switch
[B2] on switch bank S1 is pushed to the right-hand side. Configuration ID 4 is designed to model a dongle
application.
A TPS65982-EVM configured as a dongle is capable of consuming (sinking) power only. A fully-featured
Type-C port on a dongle can be capable as an upstream-facing port (UFP) for DisplayPort video, which is
also emulated by this EVM configuration.
5.3.3.5.2 Source Capabilities
This configuration is designed to be a consumer (sink) of power only, and therefore does not have any
source capabilities.
5.3.3.5.3 Sink Capabilities
This configuration is capable of negotiating PD contracts to sink 5 V at 900 milliamps through the PP_HV
internal FET path only.
5.3.3.5.4 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).
5.3.3.5.5 Ideal Connections
This configuration pairs ideally with a TPS65982-EVM using configuration ID 3 for consuming power and
entering DisplayPort alternate mode. This configuration is also compatible with a TPS65982-EVM using
configuration ID 1 for consuming power and entering DisplayPort alternate mode. These TPS65982-EVM
configurations respectively emulate notebook and tablet/Ultrabook applications and the same performance
is expected when connected to actual applications of these products.
