USB Dedicated Charging Port Controller and Current Limiting Power Switch - TPS2511


USB Dedicated Charging Port Controller and Current Limiting Power Switch



The TPS2511 is a USB dedicated charging port (DCP) controller and current limiting power switch. An auto-detect feature monitors USB data line voltage, and automatically provides the correct electrical signatures on the data lines to charge compliant devices among the following dedicated charging schemes:

  • Divider DCP, required to apply 2.7 V and 2.0 V on the D+ and D– lines respectively or 2.0 V and 2.7 V on the D+ and D– lines respectively
  • BC1.2 DCP, required to short the D+ Line to the D– Line
  • 1.2 V on both D+ and D– Lines

The TPS2511 is a 70-mΩ power-distribution switch intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device also provides hiccup mode when the output (OUT) voltage is less than 3.80 V (typ) or when an over temperature protection occurs during an overload condition. Accurate and programmable current limit provides flexibility and convenience for applications. The TPS2511 provides a CS pin for USB cable resistance compensation and an EN pin to control the device turn on and turn off.
