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
