The TMI9130E 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 3 DCP, required to apply 2.7V and 2.7V on the D+ and D- Lines respectively (SEL=IN or floated SEL);
2. Divider 2 DCP, required to apply 2.7V and 2.0V on the D+ and D- Lines respectively (SEL=GND);
3. BC1.2 DCP, required to short the D+ Line to the D– Line
4. Chinese Telecom Standard YD/T 1591-2009 Shorted Mode, required to short the D+ Line to the D– Line
5. 1.2V on both D+ and D– Lines
