TPS25762/72-Q1 EVM User's Guide
ABSTRACT
This document is the user's guide for TPS25762Q1EVM-146, TPS25772Q1EVM-149, and
TPS25772Q1EVM-150 Evaluation Modules. The EVMs allow for evaluation of the TPS25762-Q1 and
TPS25772-Q1 IC as part of a stand-alone testing kit and for development and testing of USB Type-C and Power
Delivery (PD) end products. This EVM board is designed for dual PD charging ports. According to different
components installation, it can support dual ports charging only (TPS25772Q1EVM-149), dual ports ch
USB2.0 data (TPS25772Q1EVM-150), single port charging only (TPS25762Q1EVM-146) . This EVM integrates
the TIVA microcontroller and HUB IC, these enable us to support online debugging, online updating EEPROM
and support dual ports USB2.0 data. This EVM also integrates some peripherals to implement multiple function
of TPS25762/72-Q1, such as temperature sensor, IO expander, and digital potentiometer.
