具有 CDP/SDP 自动切换功能的 USB 充电端口控制器和具有负载检测功能的 2.5A 电源开关

TPS2546 是一款集成有 USB 2.0 高速数据线路 (D+/D-) 开关的 USB 充电端口控制器和电源开关。TPS2546 可在 D+/D– 上提供电气信号，从而为下列出的充电方案提供支持。TI 使用 TPS2546 对常用的移动电话、平板电脑以及媒体设备进行充电测试，以确保其既与符合 BC1.2 的器件兼容也与不符合 BC1.2 的器件兼容。 除了支持对常用设备进行充电，TPS2546 还支持两种不同的电源管理 功能，分别为电源唤醒和端口电源管理 (PPM)（通过 STATUS 引脚实现）。电源唤醒可在 S4/S5 充电过程中实现电源控制，而 PPM 能够在多端口应用中管理端口电源 • 符合 USB 电池充电规范 1.2 的 D+/D– CDP/DCP 模式\n• 通过自动选择以下模式支持非 BC1.2 充电模式： \n• D+/D– 1.2V 模式\n• 支持休眠模式充电和鼠标/键盘唤醒\n• 负载检测（针对 S4/S5 充电过程中的电源控制以及所有充电模式下的端口电源管理）\n• 集成 73mΩ（典型值）高侧金属氧化物半导体场效应晶体管 (MOSFET)\n• 工作电压范围：4.5V 至 5.5V\n• 当器件被禁用时为 2µA\n• 与 TPS2543 可互相插接且 BOM 兼容\n• DM/DP 引脚上的静电放电 (ESD) 额定值达 8kV\n• 已通过 UL（;
