The TPS251xx devices are USB dedicated charging port (DCP) controllers. 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: 1. Divider 1 DCP, required to apply 2 V and 2.7 V on the D+ and D– Lines respectively (TPS2513, TPS2514) 2. Divider 2 DCP, required to apply 2.7 V and 2 V on the D+ and D– Lines respectively (TPS2513, TPS2514) 3. Divider 3 DCP, required to apply 2.7 V and 2.7 V on the D+ and D– Lines respectively (TPS2513A, TPS2514A) 4. BC1.2 DCP, required to short the D+ Line to the D– Line 5. Chinese Telecom Standard YD/T 1591-2009 Shorted Mode, required to short the D+ Line to the D– Line 6. 1.2 V on both D+ and D– Lines
“Texas Instrument’s USB Dedicated Charging Port Controller TPS2514 is specifically designed to implement the charging schemas mentioned below. An auto-detect feature monitors USB data line voltage and automatically provides the correct electrical signatures on D+ and D– data lines …
