Cxus7711 is a USB dedicated charging port controller. It can be used in car charger, AC-DC power adapter with USB port and other USB charging equipment. Cxus7711 has the feature of automatic detection. By monitoring the change of voltage on D + and D -, it will load correct recognizable signal on DP and DM timely, so as to realize the fast charging function of compatible portable equipment connected with it. Supported portable devices include: smart phones, 5V rechargeable tablets and personal media players. The cxus7711 supports the following five most commonly used charging protocols:
Z partial voltage 1 (apply 2V and 2.7V respectively on D + and d-lines)
Z partial voltage 2 (apply 2.7V and 2V respectively on D + and d-lines)
Z bc1.2 protocol, USB battery charging specification 1.2 revision
Z China telecom industry standard YD / T 1591-2009
Z apply 1.2V to both D + and D -
