3 Description
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 pliant 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 Tele 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
