The CXUS7714 CXUS7714A is USB dedicated charging port (DCP) controllers. Applications include vehicle power charger, wall adapters with USB DCP and
other USB chargers. The CXUS7714 CXUS7714A controller has the auto-detect
feature that monitors the D+ and D– line voltages of the USB connector,
providing the correct electrical signatures on the DP and DM pins for the
correct detections of compliant portable devices to fast charge. These
portable devices include smart phones, 5-V tablets and personal media players.
The CXUS7714 CXUS7714Asupport five of the most common protocols:
Divider 3(DCP Applying 2.7V on D+ Line and 2.7V on D– Line)
USB Battery Charging Specification, Revision 1.2 (BC1.2) Chinese
Telecommunications Industry
Standard YD/T 1591-2009 1.2V on both D+ and D– lines
