UCHQ613 Datasheet
 USB DEDICATED CHARGING PORT CONTROLLER

 

 

 

DESCRIPTION

 

The UTC  UCHQ613 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 2V and 2.7V on the D+ and D–  Lines respectively.

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

3. BC 1.2 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

 

FEATURES

 

* 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 2.7V on D+ Line And 2V on D-line (or USB DCP Applying 2V on D+ Line and 2.7V on D– Line)

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

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

* Dual USB Port Controller, UCHQ613

* Operating Range: 4.5V to 5.5V
