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