This document is the user guide for the TPS65988 Evaluation Module (TPS65988EVM). The TPS65988EVM allows for evaluation of the TPS65988 IC as part of a stand-alone testing kit and for development and testing of USB Type-C and Power Delivery (PD) end products. Out of the box, the TPS65988EVM is configured to emulate a dual-port laptop computer.

Notebook with USB 2.0, USB 3.0, and DP capabilities 4 Introduction The TPS65988 is a stand-alone USB Type-C and Power Delivery (PD) controller providing cable plug and orientation detection at the USB Type-C connector. Upon cable plug and orientation detection, the TPS65988 communicates on the CC line using the USB PD protocol.
Setup 5.1.1.1 TPS65988 Jumper Configuration Out of the box, the TPS65988EVM has jumper configuration for a TPS65988 device. With this configuration, the two internal power paths are configured as Source paths for their respective Type-C ports. The two external power paths are configured as Sink paths for their respective Type-C ports. When using the TPS65988EVM, use a TPS65988 template in the TPS6598x Application Customization Tool.
PPHV2 is used as the Source path for the Type-C port, it is connected to the net B-Var which is the Variable DC/DC used for Port B in the TPS65988 configuration. PPHV1 is used for the Sink path on the TPS65987D.
TPS65987S, the internal power path (PPHV1) is used as the Source Path and one of the external power paths is used as the sink path. The TPS65988 can be configured to act as a TPS65987S through the use of a TPS65987S Configuration Template in the TPS6598x Application Customization Tool.
S1 is located on the top-left corner of the EVM. This switch is a push-button that pulls the HRESET pin (39) of the TPS65988 high when pressed. Releasing the push-button pulls HRESET low again, and the TPS65988 goes through a soft reset, which consists of reloading firmware (FW) from RAM. If a...
S6 is located on the top right corner of the EVM. This push button switch holds the SPI Miso line to GND. This button is to be used when booting the device. If this button is pressed when the device is booting, the TPS65988 does not load its configuration from the SPI Flash, but instead boots into a default ROM configuration.
The TPS65988EVM has a dip switch (S2) that can be used to configure the I C addresses and BusPower settings of the device. Switch1 through Switch3 are used to set the I2C address of the TPS65988 by adjusting the voltage divider seen at ADCIN2. Refer to the TPS65988 datasheet to see the different I C address configurations.
The barrel jack voltage is sensed by a comparator, which drives GPIO1 (BJ_DETECT) on the TPS65988. By default, the Barrel Jack Detect is not enabled. To enable Barrel Jack Detect place R109 and refer to the TPS65988 Utilities Tool User Guide and TPS65988 Firmware User Guide.
The TPS65988EVM has two full feature USB Type-C receptacles (port A/B) and routes VBUS, SSTX and SSRX pairs, SBU1 and SBU2 pairs, and D+ and D– signals. The TPS65988 device can be used in self-powered and bus-powered configurations for added flexibility. When self-powered, the EVM can provide up to 60 W (20 V, at 3 A) of power per port via the internal high voltage power path.
5.1.11 USB Micro B Connector (J9) J9, the micro-B receptacle connects the FTDI to the PC for the TPS65988 Customization GUI. Use a standard USB micro-B to Type-A cable to make this connection. The Debug Board Enable LED turns on when VBUS is present on the FTDI board.
Figure 5-31 Figure 5-32 the highlight these features. Figure 5-31. TP1, TP2, TP3 and TP4 – CC1 and CC2 Test Points Figure 5-32. TPS65988 BMC Data TPS65988 Evaluation Module SLVUB62B – JUNE 2017 – REVISED NOVEMBER 2020 Submit Document Feedback...
VBUS test point is capable of drawing up to 3 A for an external load. Note that a PD power contract with the necessary capability must be negotiated in order to draw current from the VBUS test point. Refer to the TPS65988 Configuration Tool User Guide for configuration instructions. Figure 5-33...
(GPIO); therefore, each must be enabled separately via configuration, if configuring a custom image (see TPS65988 Configuration Tool User Guide). By default MXCTL0 LED is on when the connected device supports USB3.0, MXCTL1 LED is on when DisplayPort Alternate Mode is entered. MXCTL2 highlights the orientation of the cable.
19.78 V 5.2.3 S2 Switch Bank Functionality The I C address setting must match the configuration generated by the TPS65988 configuration tool. Table 5-5 summarizes the I C address settings. To adjust the dead battery boot behavior, the setting on ADCIN1 can be adjusted.
Out of the box, the TPS65988EVM is configured to emulate a dual-port laptop computer. Both ports are used to source or sink power, and both ports are data DFP. If different configurations are required to test your system, use the TPS65988 Application Configuration GUI tool to create a configuration or load a different configuration template.
Using a USB Type-C to Type-A cable allows for connection to a legacy USB device, such as a flash-drive. The TPS65988 can act as a host passing the DP or USB connection by using the SS MUX and USB HUB.
The following checks help resolve issues when connecting the EVM to another EVM or USB Type-C device and no status LEDs are on: • Verify that a firmware image is loaded in on the TPS65988 using the TPS65988 Configuration Tool • Verify the CC lines are toggling for Dual-Role Port functionality (see...
In compliance with the Article 33 provision of the EU REACH regulation, the user is notified that this EVM includes component(s) containing at least one Substance of Very High Concern (SVHC) above 0.1%. The substance use from Texas Instruments does not exceed 1 ton per year. The SVHCs are shown in Table 8-1.
Figure 9-3 shows the power path block, which contains the power portion of the TPS65988 and the required passives. The external power path consists of back-to-back PMOS with RCP circuit. The internal power path is used for sourcing power and the external power path is used for sinking power. The TPS65988 power path can provide power to VBUS or consume power from VBUS.
