TIDA-050047

Integrated USB Type-C® power delivery (PD) and charging reference design for 2-4 cell batteries

TIDA-050047

Design files

Overview

This reference design features charging up to 20 V at 5 A without the need for any external FETs, enabling a much smaller solution size and reducing total BOM cost. A microprocessor is also not necessary as the TPS25750 power delivery (PD) controller will handle the I2C communication to the BQ25792 battery charger IC. This I2C capability and the TPS25750 web-based GUI greatly simplify the firmware development process.

Features
  • Supports standard Type-C communication, PD negotiation, and power/data role swaps
  • Comprehensive power path management and protection plus I2C capability eliminates need for 7 FETs and microcontroller
  • Configurable as source/sink or sink-only power
  • Source mode offers on-the-go mode support
  • Best-in-class web-based GUI available for simple PD controller configuration
  • Wide input voltage range for charging a 2-4 cell battery at a current of up to 5 A
