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
● Supports USB DCP Shorting D+ Line to D– Line per USB Battery Charging Specification, Revision 1.2 (BC1.2)
● Supports Shorted Mode (Shorting D+ Line to D– Line) per Chinese Telecommunication Industry Standard YD/T 1591-2009
● Supports USB DCP Applying 2.7 V on D+ Line and 2 V on D– line (or USB DCP Applying 2 V on D+ Line and 2.7 V on D– Line) (TPS2513, TPS2514)
