具有負(fù)載檢測功能的 USB 充電端口控制器和 3A 電源開關(guān)

TPS2547 是一款集成有 USB 2.0 高速數(shù)據(jù)線路 (D+/D-) 開關(guān)的 USB 充電端口控制器和電源開關(guān)。TPS2547 可在 D+/D– 上提供電氣信號，從而為特性 說明部分中列出的充電方案提供支持。TI 使用 TPS2547 對常用的移動電話、平板電腦以及媒體設(shè)備進(jìn)行充電測試，以確保其既與符合 BC1.2 的器件兼容也與不符合 BC1.2 的器件兼容。\n\n除了支持對常用設(shè)備進(jìn)行充電，TPS2547 還支持兩種不同的電源管理 功能，分別為電源喚醒和端口電源管理 (PPM)（通過 STATUS 引腳實(shí)現(xiàn)）。電源喚醒允許在 S4/S5 充電中進(jìn)行電源控制，PPM 支持在多端口系統(tǒng) ? 符合 USB BC 1.2 規(guī)范的 D+/D– CDP/DCP 模式\n? 符合中國電信行業(yè)標(biāo)準(zhǔn) YD/T 1591-2009 的D+/D– 短路模式\n? 通過自動選擇以下模式支持非 BC1.2 充電模式： \n? D+/D– 分壓器模式（2V/2.7V 和 2.7V/2V）\n? D+/D– 1.2V 模式\n \n? 支持休眠模式充電和鼠標(biāo)/鍵盤喚醒\n? 負(fù)載檢測（針對 S4/S5 充電過程中的電源控制以及所有充電模式下的端口電源管理）\n? 可兼容 USB 2.0 和 3.0\n? 集成 73mΩ（典型值）高側(cè)金屬氧化物半導(dǎo)體場效應(yīng)晶體管 (MOSFET)\n? 3A 可編程 I;
