TPS25820 Overview
The TPS25820/21 is a USB Type-C source controller with an integrated 1.5 A-rated USB power switch. The TPS25820/21 monitors the Type-C configuration channel (CC) lines to determine when a USB sink is attached. If a sink is attached, the TPS25820/21 applies power to VBUS and municates the selectable VBUS current sourcing capability to the sink via the pass through CC line.
