Single USB Charger Port Controller

Converter

 

 

 

DESCRIPTIONS

 

The EC49021 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:

 

Divider 1 DCP, required to apply 2 V and 2.7 V on the D+ and D– Lines respectively.

Divider 2 DCP, required to apply 2.7 V and 2 V on the D+ and D– Lines respectively.

BC1.2 DCP, required to short the D+ Line to the D– Line

Chinese Telecom Standard YD/T 1591-2009 Shorted Mode, required to short the D+ Line to the D– Line.

1.2 V on both D+ and D– Lines.

​​ 

 

FEATURE

 

​​ Supports USB DCP Shorting D+ Line to D- Line per USB Battery Charging Specification, Revision 1.2(BC1.2).

​​ 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).

​​ Supports USB DCP Applying 1.2 V on D+ and D– Lines.

​​ Automatically Switch D+ and D- Lines Connections for an Attached Device.

​​ Operating Range: 4.5 V to 5.5 V.

​​ Available in SOT23-5 ​​ Package.
