CXUS7732 USB充电端口控制器集成了USB 2.0高速数据线D+/D-开关和电源开关支持睡眠模式充电和LS&HS HID鼠标/键盘唤醒S4/S5充电电源控制

CXUS7732是一个USB充电端口控制器，集成了USB 2.0高速数据线（D+/D-）开关和电源开关。充电方案符合电池充电BC1.2和中国电信行业标准YD/T 1591-2009。CXUS7732还实现了一些支持非BC1.2兼容设备的专用充电方案，如divider1、divider2模式或1.2V短路模式。CXUS7732通过支持电源管理的状态引脚提供电源唤醒和端口电源管理（PPM）。电源唤醒允许S4/S5充电中的电源控制，PPM允许在多端口应用中管理端口电源。此外，CXUS7732支持从S3唤醒鼠标/键盘。具有电流限制和短路保护的62MW功率开关支持负载电流达到2.5A。由两个编程引脚设置的两个限流阈值在电流限制和负载检测设置中提供灵活性。

The CXUS7732 is an USB charging port controller which integrates USB 2.0 high-speed data line (D+/D-) switches and a power switch. The charging schemes comply with battery charging BC1.2 and Chinese Telecommunications Industry Standard YD/T 1591-2009. The CXUS7732 also implements some dedicated charging schemes to support non-BC1.2 compatible device, such as divider1, divider2 mode or 1.2V shorted mode. The CXUS7732 features power wake and port power management (PPM) via STATUS pin in supporting power management. Power wake allows for power supply control in S4/S5 charging and PPM the ability to manage port power in a multi-port application. Furthermore, the CXUS7732 supports mouse/keyboard wake up from S3. The 62mW power switch with current limit and short circuit protections supports load current up to 2.5A. Two current limit thresholds set by two programming pin provide flexibility in current limit and load detection settings
