Description

General part information

TPS254900A-Q1 Series

The TPS254900A-Q1 device is a USB charging-port controller and power switch with short-to-battery protection. This feature provides protection on OUT, DM_IN and DP_IN. These three pins withstand voltage up to 18 V.

The internal MOSFET turns off quickly when the short-to-battery condition occurs. Rapid turnoff is very important to protect the upstream DC-DC converter, processor, or hub data lines.

The TPS254900A-Q1 has a low UVLO of 3.5 V, so that the power switch does not turn off during start-stop.
