3 Description

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

via the pass through CC line. If the sink is attached

with an electronically marked cable, the TPS25820

2.0 and data-less charging implementations.

The TPS25820/21 draws 1.0 μA (typ) when nothing is

attached. The FAULT output signals when the switch

is in an overcurrent or overtemperature condition. The

SINK output signals when a sink is attached and the

POL output signals the polarity of the cable super-

speed lines.
