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 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
