TPS254900-Q1 USB Charging Port Controller

Texas Instruments TPS254900-Q1 USB Charging Port Controller 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 voltages up to 18V. The internal MOSFET turns off quickly when the short-to-battery condition occurs. This rapid turnoff is very important to protect the upstream dc-dc converter, processor, or hub data lines. The TPS254900-Q1 45mΩ power switch has two selectable, adjustable current limits. These limits 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.
