Description
AI
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 VBUSand communicates the selectable VBUScurrent sourcing capability to the sink via the pass through CC line. If the sink is attached with an electronically marked cable, the TPS25820 also applies VCONNpower to the cable VCONNpin. The TPS25821 does not apply VCONNpower and is for functions where VCONNis not needed such as USB 2.0 and data-less charging implementations.
The TPS25820/21 draws 1.0 µA (typ) when nothing is attached. TheFAULToutput signals when the switch is in an overcurrent or overtemperature condition. TheSINKoutput signals when a sink is attached and thePOLoutput signals the polarity of the cable super-speed lines.
