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.
The TPS254900A-Q1 45-mΩ power switch has two selectable, adjustable current limits that support port power management by changing to a lower current limit when adjacent ports are experiencing heavy loads. This is important in systems with multiple ports and upstream power supplies with limited capacity.
The TPS254900A-Q1 device has a current-sense output that is able to control an upstream supply, which allows it to maintain 5 V at the USB port even with heavy charging currents. This feature is important in systems with long USB cables where significant voltage drops can occur with fast-charging portable devices.
A current monitor allows a system to monitor the load current in real time by monitoring the IMON voltage. The current monitor is very useful and can be used for dynamic port-power management.
The TPS254900A-Q1 device also provides ESD protection capability per IEC 61000-4-2, level 4 on DP_IN and DM_IN.
