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:

• 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)
• Supports USB DCP applying 2.7 V on D+ line and 2.7 V on D- line (TPS2513A, TPS2514A)
• Supports USB DCP applying 1.2 V on D+ and D– Lines
• Automatically Switch D+ and D– Lines Connections for an Attached Device
• Dual USB Port Controller (TPS2513, TPS2513A)
