Introduction

1 Introduction

Texas Instrument's (TI’s) TPS65987-90 evaluation module helps designers evaluate the operation and
performance of the TPS65987 device.

The TPS65987 device is a USB Type-C and Power Delivery (PD) controller providing cable plug and
orientation detection at the USB Type-C connector. Upon cable detection, the TPS65987 communicates
on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete,
the TPS65987 device enables the appropriate power path and configures Alternate Mode settings for
external multiplexers. The TPS65987D device has two internal power paths that can source or sink up to 5
A. The EVM is customizable through the TPS65987 Application Customization Tool. Additionally, the EVM
is equipped with an FTDI chip for flashing a new project through SPI or I2C for debugging and
development.

Figure 1 shows the TPS65987-90EVM board and Figure 2 shows a block level diagram.

Setup

2.1 Jumper Configuration

Out of the box, the TPS65987_90EVM is configured to use TPS65987's PPHV1 as sink path (J4) and
PPHV2 as source path (J6), which matches the configuration of firmware already programmed in the
device. Using Application Customization Tool each of this power path can be programmed as either
source or sink.

Remember, the jumper configuration in the hardware must match the source and sink paths in the
software, Application Customization Tool (GUI). See Figure 3 and Table 1 for the jumper configuration.

2.2 Connector Functionality

Table 2 lists the TPS65987-90EVM connector and functionality.

Designator Description

J1 USB Type-C connector: TI recommends using an active or e-marked USB Type-c cable
J2 Expansion board connector: Connect the DP-EXPANSION-EVM to evaluate DisplayPort and USB3.2 data
J3 Micro-B connector: Connect to a PC to flash a project on the PD controller. You must download the

Application Customization Tool (GUI) to flash a project properly.

J9 Barrel jack connector: Use a 19-V to 20-V DC supply. A standard Dell or HP notebook adapter (or similar) will

provide the required power.

Setup

2.5 Switches

Table 5, Table 6, and Table 7 lists the TPS65987-90EVM switches. For S1, make sure to leave all six

switches in the ON position (to the right) for flashing a project and debugging. For S4 Switch: EVM out of
th box should have S4->4 (BP_WaitFor3V3_Internal) as on(right). This ensures that PD controller enables
internal paths in dead battery mode. This switch can be turned off(left) if EVM is used as source only.

when pressed. Releasing the push-button pulsl HRESET low again, and the TPS65987D
device goes through a soft reset, which consists of reloading firmware from RAM. If a valid
configuration is present in RAM, the TPS65988 device will not reload configuration from the
external flash.

This push button switch will hold the SPI Miso line to GND. Use this button when booting the
device. If this button is pressed when the device is booting, the TPS65987D device does not
load its configuration from the SPI Flash and instead boots into a default ROM configuration.

3 Using the TPS65987-90EVM

This section discusses how to power the EVM, configure the firmware, and how to debug.

3.1 Powering the TPS65987-90EVM

The main power supply for the EVM is the barrel jack (J9), which accepts 19 V to 20 V via a barrel jack
adapter. The EVM can also be powered with an external power supply on SYS_PWR (pin 1 of J4, J5, J6,
or J7). The input voltage can range from 5 V to 20 V, but configure the appropriate power profile for
PP_HV in the firmware using the configuration tool. The EVM can also be powered as a sink through a
USB Type-C cable from a source adaptor, EVM, or device.

3.2 Firmware Configurations

Out of the box, the TPS65987-90EVM is configured to emulate a single port laptop computer. This
configuration can be used to source or sink power known as (DRP), and this configuration sets DFP_D
(Downward Facing Port). on DP expansion connector a DP_EXPANSION (source) EVM can be connected
to test Display port alternate mode. If different configurations are required to test your system, use the
TPS65987_8 Application Configuration Tool (GUI) to create a configuration or load a different
configuration template.

3.3 Debugging the EVM

The following checks can help resolve issues when connecting the EVM to another EVM or USB Type-C
device and no status LEDs are on:

• Make sure that a firmware image is loaded on the TPS65987-90EVM, using the TPS65987_8
Application Configuration Tool (GUI).

• Make sure the CC lines are toggling for dual-role port functionality.

• Make sure the following system supplies:
– P3V3 = 3.3 V
– P5V0 = 5 V
– Barrel jack / SYS_PWR = 20 V (when plugged in)
– VAR_DCDC = 5 V (when barrel jack is plugged in without a USB Type-C attached cable or device)
– V

= 5 V, 9 V, 15 V, or 20 V (when USB Type-C port is attached to another EVM or device)
