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.

2.5 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.

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)

During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit components may have elevated case temperatures. These components include but are not limited to linear regulators, switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the information in the associated documentation. When working with the EVM, please be aware that the EVM may become very warm.

4.3.2 EVMs are intended solely for use by technically qualified, professional electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems, and subsystems. User assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees, affiliates, contractors or designees. User assumes all responsibility and liability to ensure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. User assumes all responsibility and liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or designees.

4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal, state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local requirements.
