Setup

5.3.3.4 Configuration ID 3: Notebook (or Mobile Workstation) That can Pass AC-Adapted Power

Table 6. Configuration ID 3

5.3.3.4.1 Overview

The TPS65982-EVM will boot up and initialize into configuration ID 3 when the 1

and 2

DIP switches

[B0] and [B1] on switch bank S1 are pushed to the right-hand side and the 3

and 4

DIP switch [B2] and

[B3] on switch bank S1 is pushed to the left-hand side. Configuration ID 3 is designed to model a

notebook (or mobile workstation) application that can pass AC-adapted power as a provider.

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, 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.

5.3.3.4.2 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 20 V at 3 A through the PP_EXT external FET path.

5.3.3.4.3 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_HV internal FET path.

5.3.3.4.4 Video Capabilities

This configuration is 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 DisplayPort video as an upstream-facing port (UFP).

5.3.3.4.5 Ideal Connections

This configuration pairs ideally with a TPS65982-EVM using configuration ID 0 for consuming or providing

power and entering DisplayPort 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.
