FEATURES  
DESCRIPTION  
The TPS2513 and TPS2514 are USB dedicated  
Supports USB DCP Shorting D+ Line to  
D– Line per USB Battery Charging  
Specification, Revision 1.2 (BC1.2)  
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 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)  
1. Divider 1 DCP, required to apply 2 V and 2.7 V  
on the D+ and D– Lines respectively  
2. Divider 2 DCP, required to apply 2.7 V and 2 V  
on the D+ and D– Lines respectively  
Supports USB DCP Applying 1.2 V on  
D+ and D– Lines  
3. BC1.2 DCP, required to short the D+ Line to the  
D– Line  
Automatically Switch D+ and D- Lines  
Connections for an Attached Device  
4. Chinese Telecom Standard YD/T 1591-2009
