USB Type-C™ Power-Path Protection With Audio Accessory Support Reference Design

TIDA-03030

Design files

Overview

The TIDA-03030 reference design provides a robust protection solution for the power path in USB Type-C™ applications. The design protects the power path from overvoltage, overcurrent, hot-plug, and reverse-current events by leveraging the TPS25923 (eFuse) and CSD17571Q2 (reverse-blocking FET). The system solution emulates a downstream facing port (DFP) and is able to detect the connection of an upstream facing port (UFP) device. The TIDA-03030 reference design also supports analog audio for USB Type-C audio accessories. The flexible VBUS protection with audio accessory functionality is achievable within a 20 mm x 20 mm, four-layer, single-sided solution.

Features
  • Reverse current blocking and overvoltage protection up 30 V
  • Overcurrent events and short-circuit protection
  • Determines UFP connection, audio accessory, port attachment, and cable orientation
  • Automatically switches between analog audio and USB data lines
  • Routes MIC and GND signals automatically

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
