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.
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.
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.

Simulating an UFP Device on the TPS25810EVM-745 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.
UFP# POL# Figure 9. Simulating an UFP Device on the TPS25810EVM-745 With and Without an Output Load 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.
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.
Rd resistor. This mode can be used for factory testing or similar functional modes. Board Layout The following images show the silkscreen, top, bottom, and assembly layers of the TPS25810EVM-745. Figure 14. Top Silkscreen SLVUAI0A – September 2015 – Revised September 2015...
