1.1 Introduction

The TPS25751AEVM is an evaluation module designed to facilitate comprehensive assessment of the TPS25751A in both standalone configurations and USB Type-C and power delivery (PD) applications. The TPS25751A features integrated managed power paths with robust protection for complete USB-C PD designs. Additionally, the device integrates I2C communication control for external battery charger integrated circuits (ICs), adding ease of use and accelerating time to market. This user's guide provides detailed information for evaluating and implementing the TPS25751A evaluation module.

The following is a continuation of the features list:

  • Support integration with the following BQ EVMs
    • BQ25756, BQ25756E, BQ25792, BQ25798, BQ25731, BQ25713, and BQ25690
    • 100W (20V:5A) source and 100W (20V:5A) sink with BQ25756(E)EVM for 1S-14(7)S battery applications
    • 45W (20V:2.25A) source and 60W (20V:3A) sink with BQ25792/8EVM for 1S-4S battery applications
    • 100W (20V:5A) source and 100W (20V:5A) sink with BQ25731EVM for 1S-5S battery applications
