4 Introduction

The TPS65981 device is a stand-alone USB Type-C and Power Delivery (PD) controller providing cable­plug and orientation detection at the USB Type-C connector. Upon cable detection, the TPS65981 device
communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation
are complete, the TPS65981 device enables the appropriate power path and configures alternate mode
settings for internal and (optional) external multiplexers.

This user's guide describes the TPS65981EVM and its capabilities with the DP-EXPANSION-EVM. This
guide also contains testing procedures of various PD power and alternate mode configurations. The EVM
comes with preloaded firmware for out-of-the-box functionality and is also customizable through the
TPS6598x Application Customization Tool. Additionally, the EVM has a USB micro-B and Aardvark to SPI
or I2C interface for debugging and development. The TPS65981EVM is a module based design, allowing

5 Setup

This section describes the various EVM features and how to test the various configurations.

5.1 Switch, Connector, and Test Point Descriptions

5.1.1 Switch Banks

5.1.1.1 S1: Configuration Switch

The S1 switch bank is used to configure the EVM. By default, all switches should be placed in the right or
off (pulled down to GND) position. The top switch is tied to BUSPOWERZ and allows the EVM to be
powered from dead battery using different the different power paths. The second, third, and fourth
switches are bits 0, 1, and 2, respectively. These switches are reserved for future use and, currently,
should always be set right. Bit 0, bit 1, and bit 2 are connected to DEBUG_CTL1, GPIO6, and GPIO5,
respectively. The left or high position is pulled up through an 11-kΩ resistor to LD0_3V3.

5.1.1.2 S3: FTDI Enable and Disable

The switches labeled 3.3V EN and 5V EN pass the supply from the FTDI board to the J8 header. These
two switches should be disabled by default and should be in the down position.

The BP Enable and Force Enable switches control the reset on the FTDI device. When BP Enable is set
high, the TPS65981 device holds the FTDI in reset until it has successfully loaded the firmware. When set
low, a weak pulldown on the FTDI reset pin occurs, holding the device in reset. This switch should be set
low by default in the down position.

The Force Enable switch has a weak pullup to the board 3.3-V supply to always enable the FTDI device
and a weak pull down on the FTDI reset pin which holds the device in reset when switched low. This
switch should be set high in the up position by default.

Setup

5.1.2 Connectors

5.1.2.1 J1: Barrel-Jack Power Connector

The barrel-jack power connector accepts a 19-V to 20-V DC supply. A standard Dell or HP notebook
adaptor (or similar adapter) provides the required power. This input provides the SYS_PWR with 19 V to
20 V for high-power PD contracts up to 60 W. Be sure to select an appropriate power adapter that is
capable of 60-W operation. For example, the Dell 130W part number, 492-BBGP, could be used.

The TPS65981EVM is capable of requesting a power-role swap when the barrel jack is connected on an
EVM that is currently bus powered. This is valid for the configurations that are capable of delivering power.
The barrel-jack voltage is sensed by a comparator, which drives GPIO2 on the TPS65981 device. To
enable barrel-jack detect or other GPIOs, refer to the TPS6598x Utilities Tool User's Guide and

TPS65981, TPS65982, and TPS65986 Firmware User’s Guide (SLVUAH7).

Setup

5.1.2.2 J3 and J8: Headers

These headers allow the EVM to be connected to any debug board. Additionally, this allows the left and
right halves of the board to be stacked, which produces the equivalent connections prior to breaking off.
See Figure 27 for names of all connections.

NOTE: Some of the header pins are not connected unless a 0-Ω option resistor is placed.

5.1.2.3 J4: Expansion Board Connector

The connector routes the power, SSTX/RX, USB_RP_P/N, AUX_P/N, HPD, I2C, and GPIO control signals
for the DP-EXPANSION-EVM.

5.1.2.4 J5: Type-C Connector

This receptacle is a full-feature port, with power, SSTX/RX, SBU1/2, and DP/N signals. The TPS65981
device can be used in self-powered and bus-powered configurations for added flexibility. When self­powered, the EVM can provide up to 60 W of power (20 V/3 A). The EVM is also capable of sinking 60 W
of power (20 V/3 A) when device is powered or in dead battery or consumer mode.

5.1.2.5 J6: Power Path Connector

This connector allows jumpers to be placed based on which paths are being used for sourcing and
sinking. When using the default firmware, the Variable DC/DC pin (bottom-middle) should be connected to
the PP_HV pin (left) and the Barrel Jack pin (top-middle) should be connected to PP_EXT (right). See

Figure 23 and the EVM labeling for the pin locations and routing.

www.ti.com

5.1.2.6 J11: Debug Connector

This connector is only used for TI testing purposes.

5.1.2.7 J13: USB micro-B Connector

J13 is the USB connection to the PC for the TPS6598x Utilities GUI and TPS6598x Application
Customization Tool. A standard USB micro-B to Type-A cable can be used to connect the EVM to the
USB port on a computer.

5.1.2.8 J14: Aardvark Connector

This connector matches the Aardvark I2C or SPI master that allows the user to access the I2C and SPI
pins on the TPS6598x EVM. In other words, this allows the user to use the TotalPhase Aardvark.

NOTE: The FT4323 will load the I2C or SPI pins when powered. TI recommends leaving the FT4323

in reset by having the Force Enable and BP Enable switches in the off (down) position.

5.1.3.3 TP5: VBUS Test Point

The VBUS test point is used to measure VBUS at the connector. With PD power possibly going up to 20
V, use caution when connecting and disconnecting probes on the TPS65981EVM. The VBUS test point is
capable of drawing up to 3 A for an external load. A PD-power contract with the required capability must
be negotiated to draw current from the VBUS test point. Refer to the TPS6598x Application-Customization

Tool User Guide (SLVUAR8) for configuration instruction. Figure 2 shows the VBUS voltage during PD-

power negotiation.

www.ti.com

6 Using the TPS65981EVM

This section describes the EVM configurations on the preloaded firmware, getting started, and debugging
the EVM.

6.1 Powering the TPS65981EVM

The main power supply for the EVM is J1 barrel jack, which accepts 19 V to 20 V through a barrel jack
adaptor. The EVM can also be powered with an external power supply on J6. The input voltage can range
from 12 V to 20 V, but the appropriate power profile should be configured in the firmware using the
configuration tool. The EVM can also be powered from a TI MCU LaunchPad Development Kit by placing
0-Ω resistors (see Figure 18). If powering with a LaunchPad Development Kit, the EVM does not support
high-voltage contracts or provide high currents at 5 V because of the limited power capability. The EVM
can also be bus powered from the Type-C connector and accepts 5 V to 20 V on VBUS, depending on the
sink configuration.

Using the TPS65981EVM

Table 2. PDO LED Functions

6.2 Firmware Configurations

The EVM is shipped with a preloaded firmware image that supports various Type-C and PD products:
dock and notebook. The firmware is loaded at start-up and the configuration is defined by the state of the
third switch on the S1 configuration switch (see Section 5.1.1.1). The top three switches in the switch bank
represent B0, B1, and B2, respectively. Table 3 lists the configurations on the EVM.

6.3 Connecting the TPS65981EVM

Various Type-C cables can be used to connect the EVM to a legacy Type-A host, legacy Type-A device,
or Type-C device.

6.3.1 Connecting to a Legacy Type-A Host

Using a Type-A plug to Type-C cable allows connection to a legacy host. When the billboarding and
endpoint functions are enabled on the EVM, the user can access the registers and update the firmware by
using the TPS6598x Utilities GUI. The EVM can be powered from the Type-A to Type-C cable and does
not require a power-supply function with the TPS6598x Utilities GUI. Figure 3 shows how the TPS65981
device is connected to a notebook with the TPS6598x Utilities GUI.

Figure 3. Connecting EVM to Legacy Host

6.3.2 Connecting to a Legacy Type-A Device

Using a Type-C to Type-A receptacle cable allows for connection to a legacy USB device, such as a flash­drive. The TPS65981 device cannot act as a host but can pass the USB connection to a host by using the
DP-EXPANSION-EVM (DisplayPort source board). Figure 4 shows how the notebook, DP-EXPANSION­EVM, TPS65981EVM, cable, and flash drive are connected

www.ti.com

Figure 4. Connecting EVM to Type-A Device

6.3.3 Connecting to Type-C Devices

Using a Type-C cable allows for connection to a Type-C device or host. When two TPS65981EVMs are
used with the DP-EXPANSION-EVM (source and sink boards), a complete Type-C system can be verified.
The DisplayPort alternate mode is entered when the two setups appropriately configure as defined in

Table 3. The source setup requires a USB source with DisplayPort to provide data to the sink board. A

monitor can be connected to sink board, along with a USB device to connect to the source board. Figure 5
shows how the boards are connected.

Figure 23 shows the power path block of the TPS65981 and the required passives.

TPS65981EVM Schematic

Figure 24 shows the power-supply block, which has all of the board supplies generated and the comparator circuit for barrel jack detection. The

P3V3 rail is on in bus-powered and self-powered conditions, and it has the ability to operate at 4 V to compensate for IR drop through the Type-C
cable. The P5V supply can operate at 4.5 V at 100% duty cycle, but it is intended to supply the 5 V at 3 A when the barrel jack (J4) is connected to
the EVM only. USB_5V is supplied by a boost converter from the main 3.3-V rail and is intended to ensure there is 5 V for the USB DFP port on
the DP-EXPANSION_EVM, when acting bus-powered or self-powered.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
