4 Powering Up the EVM
The TPS25810 has three input power sources: IN1, IN2, and AUX. IN1 and IN2 are the power lines that
provide power to the OUT pins, all the way through to the USB Type-C port. The aux line is power source
for the internal logic of the TPS25810. The two ways to power up these three lines are: using a 5-V/3-A
power adaptor (with J4) or using the four cable inputs (J10 for IN1, IN2 and J12 for AUX, GND) to
individually test different voltages for each power line. Use jumpers J2, J5, J9 in order to choose between
which power source to use. See Figure 3 for jumper orientation.

Powering Up the EVM www.ti.com
TI recommends a power adaptor that is a standard 2.1-mm DC power adaptor with a negative tip that can
support 5 V and 3 A. An example of a power adaptor to use is the Triad Magnetics WSU050-3000-R wall
power supply.
When using the four-cable input power source, make sure to stay within the specified voltage limits for
each port listed in the data sheet.
4.1 Measuring TPS25810 Power Consumption
The TPS25810 is powered through the AUX pin while the IN1 and IN2 lines directly power the OUT pin of
the device. Therefore an easy way to measure the power consumption is to connect an ammeter to
jumper J9. Figure 4 shows how to connect the ammeter to the AUX pin and to either the power adaptor or
the power cable (depending on how the EVM is powered).
When no device is connected to the USB port on the EVM, the TPS25810 only consumes 5 μA. To test
this have the ammeter connected properly to jumper J9, remove jumper on J1 to disconnect the LEDs,
and make sure nothing is connected to the output of the TPS25810.
Figure 4. Connecting the Ammeter to AUX Pin and Power Source
5 Enabling and Configuring the TPS25810
5.1 Enabling and Disabling the TPS25810
The TPS25810 has an enable pin that creates a convenient way to turn on or turn off the device without
interrupting the power source. On the TPS25810EVM-745 the TPS25810 can be enabled and disabled
using jumper J6. See Figure 5 for enable and disable positions for jumper J6.

5.2 Configuring the Broadcast Current Limit on the TPS25810
The TPS25810 can also advertise (using the CC lines) how much current it can supply to a connected
USB device. The three levels of current limits that the TPS25810 can support are: STD, 1.5 A, and 3 A.
To switch between these three levels, a HIGH or LOW voltage is set onto pins CHG and CHG_HI of the
TPS25810. Refer to the data sheet for voltage levels required for CHG and CHG_HI to change the current
limit levels. On the TPS25810EVM-745 jumpers J8 and J11 control the voltage level of CHG and CHG_HI
pins respectively. Figure 6 shows how to set up the jumper connections in order to get the desired current
limit broadcasted through the CC lines.

TPS25810EVM-745 Features www.ti.com
6 TPS25810EVM-745 Features
The TPS25810EVM-745 allows for all the features of the TPS25810 to be tested with and without a USB
Type-C cable and external device. Below are the most common types of situations that can happen with
the TPS25810EVM-745 and within each section is an explanation of how to test each situation with and
without external components. Keep in mind how the test jumpers J13 and J14 (which control CC1 and
CC2 respectively) connect to the TPS25810 and the resistors. See Figure 7 to see how they are
connected.
Figure 7. Schematic Showing How CC1 and CC2 are Connected to Jumpers J14 and J15 Respectively
CAUTION
When connecting a physical USB Type-C cable into the port of the EVM make
sure to disconnect the jumpers (J13, J14) and disconnect any loads on the
jumper J7 (which is connected to OUT pin) in order to avoid interference on the
CC lines.
6.1 No Connection to EVM
When nothing is connected to the output of the EVM then the TPS25810 will not output any power over
the OUT lines. In this mode, the TPS25810 will only consume 5 μA.
In terms of replicating this on the EVM, make sure that nothing is connected to jumpers J13, J14, and J7
which control what is connected to CC1, CC2, and OUT respectively.
6.2 Connecting a DFP Device
The TPS25810 is a downstream facing port (DFP) controller and continuously monitors the CC lines to
see if an upstream facing port (UFP) device is connected. The way it determines if an UFP device is
connected is if the CC lines are connected to a specific set of resistors values. When connecting one DFP
device to another DFP device, both devices will continue to monitor the CC lines for a valid connection
and will not turn on the output lines. This can be tested on the EVM by connecting a DFP device to the
TPS25810EVM-745 or by connecting 2 TPS25810EVM-745 together through the USB port.
6.3 Connecting a UFP Device
There are two types of UFP devices that can be connected to a DFP device: a powered UFP device or a
nonpowered UFP device. As soon as a UFP device is connected to the EVM, the UFP# LED will light up.
The way the TPS25810 detects a UFP device is by sensing if only one of the CC lines is connected to a
Ra resistor value. And if the UFP device is powered than the other CC line should be connected to a Rd
resistor value. The TPS25810EVM-745 will also report via the USB Type-C cable’s polarity/orientation with
the POL# signal and LED. To test these two types of UFP devices along with their different cable
polarities on the EVM set the CC1, CC2, and OUT jumpers based on Figure 8.Figure 8 also shows how
POL# and UFP# LEDs will behave based on the jumper connections.

6.3.1 UFP Load Detect Feature
When a UFP device is connected to the TPS25810, it is also possible to test the load detect feature. The
load detect feature is enabled when the CHG and CHG_HI pins are set HIGH to Vaux. Once a UFP
device is connected and that device exceeds the current limit (1.95 A), the LD_DET signal will be
activated. To simulate a load detect without a USB Type-C cable, it is recommended to connect a rheostat
that can support up to 15 to 20 W. Since the output is around 5 V, a resistive load of 2 Ωshould trigger
the “LD_DET#” signal. Figure 9 shows how the LD_DET# signal/LED is activated when the OUT jumper is
connected to a load that exceeds the current limit.

6.4 Connecting a Non-UFP Powered Device
The way the TPS25810 detects a powered device is by checking if one of the CC lines is connected to a
Rd resistor value. To test a connection to a non-UFP powered device on the EVM set the CC1 and CC2
jumpers and the out connection based on Figure 10. Note that the UFP# and POL# LEDs will not light up
with a non-UFP powered device since no signals from the TPS25810 are triggered.

6.5 Connecting an Audio Accessory Device
The TPS25810 can detect if an audio accessory device has been connected. It is detected by checking if
both CC lines are connected to a Ra resistor value. This connection is unique in the sense that both Ra
resistors must be connected to the CC lines within a small time frame (usually about 10 ms). The easiest
way to test this mode on the TPS25810EVM-745 is by connecting an audio accessory device through the
USB port. Figure 11 shows which LEDs are switch on when having both CC jumpers connected to Ra
after a power cycle.
Figure 11. Simulating an Audio Accessory Device on the TPS25810EVM-745
6.6 Connecting a Debug Accessory Device
The TPS25810 can detect if a debug accessory device has been connected. It is detected by checking if
both CC lines are connected to a Rd resistor value. This connection is unique in the sense that both Rd
resistors must be connected to the CC lines within a small time frame (usually about 10ms). The easiest
way to test this mode on the TPS25810EVM-745 is by connecting a debug accessory device through the
USB port. Figure 12 shows which LEDs are switch on when having both CC jumpers connected to Rd
after a power cycle.
Figure 12. Simulating a Debug Accessory Device on the TPS25810EVM-745
6.7 Connecting to a Previous USB Version
The TPS25810EVM-745 supports previous USB versions with the help of the TPS2513 which will send
the necessary power to devices that charge using the data lines (D+ and D–). The TPS2513 can support
USB 2.0 and USB 3.0 devices. For more information about the TPS2513 refer to the TPS2513 data sheet,
SLVSBY8. Note that in order to connect a previous USB version to the EVM, a USB Type-C adaptor will
be needed. In order to enable or disable the TPS2513 connect or disconnect jumper J15. Figure 13 shows
the schematic connection for the TPS2513 on the TPS25810EVM-745.

TPS25810 Output Signals www.ti.com
7 TPS25810 Output Signals
7.1 Fault Detected (FAULT#)
There are two conditions that can cause this fault signal to occur. Those two conditions are:
1. The output of the TPS25810 exceeds the programmed current threshold
2. The device exceeds the temperature threshold
As soon as the current and the temperature go back into normal ranges the fault is cleared and the device
resumes normal operation.
Refer to Electrical Characteristics section located in the TPS25810 data sheet, SLVSCR1, for more
information on the current and temperature thresholds.
7.2 Load Detected (LD_DET#)
When the device is in high current charging mode (set when the CHG and CHG_HI pins are pulled to
Vaux or logic HIGH) the device will monitor the charging current. As soon as the current exceeds 1.95 A
(typical) the LD_DET pin will be asserted.
When activated, this signal can be used to warn a microprocessor or even another TPS25810 device to
avoid over current or over power from the power source.
7.3 Upstream Facing Port Connected (UFP#)
This pin is active when an upstream facing port (UFP) device is connected to the port and is
communicating properly through the CC lines. Refer to Table 2 to see what conditions for the CC lines are
necessary to activate this mode.

7.5 Audio Accessory Mode (AUDIO#)
USB Type-C specifications defines an audio adapter decode state which allows implementation of an
analog USB Type-C to 3.5 mm headset adapter. This pin is activated when the TPS25810 detects an
audio accessory device which occurs when both CC lines are attached to the Ra resistors.
7.6 Debug Accessory Mode (DEBUG#)
USB Type-C specifications supports an optional debug accessory mode used for debug only and should
not be used for communicating with commercial products. The pin is asserted when both CC lines are
connected to the Rd resistor. This mode can be used for factory testing or similar functional modes.

www.ti.com PCB Layout Recommendations
10 PCB Layout Recommendations
• Keep input capacitors as close as possible to the IC
• USB protocol recommends having an input capacitance of 120μF
• The resistor attached to the reference pin and ground pin of the device has several requirements:
– It is recommended to have a 1% 100-kΩresistor.
– It should be connected to pins REF and GND (pin 9 and pin 10 respectively). Note that there are
two GND pins, the pin closest to the REF pin is the correct pin to connect to.
– The connection between the resistor and the GND pin should be isolated from the GND plane. See
Figure 19.
Figure 19.
• Pullup resistors should be 100 kΩ
• Keep the CC lines close to the same length
• Have the input and output traces as short as possible and wide enough for 3A (6A is using two
