TPS2540/40A 和 TPS2541 集成了带限流功能的 USB 端口电源开关、USB 2.0 高速数据线(D+/D-)开关及 USB 充电端口识别电路,适用于笔记本 PC 及其他智能 USB 主机设备。宽带宽(2.6 GHz)数据线开关具有低电容和低导通电阻,可最大限度降低信号传输的边沿与相位失真。TPS2540/40A/41 监测 D+ 和 D-,并与兼容客户端设备提供正确的信号握手协议。

TPS2540/40A/41 支持以下充电逻辑方案:

  • USB 2.0 BC1.2
  • 中国电信标准 YD/T 1591-2009
  • 分频器模式(Divider Mode),兼容 Apple 设备(如 iPod 和 iPhone)

CTL1~CTL3 逻辑输入用于从 TPS2540/40A 和 TPS2541 所提供的多种充电模式中选择其一。这些充电模式允许主机设备在以下端口之间主动切换:专用充电端口(DCP,模拟墙壁适配器)、充电下游端口(CDP,支持 1.5 A 充电电流的有源 USB 2.0 数据通信)或标准下游端口(SDP,支持 500 mA 电流的有源 USB 2.0 数据通信)。此外,TPS2540/40A/41 还集成了自动检测功能,该功能同时支持符合 BC1.2 规范的 DCP 方案和分频器模式(Divider Mode),无需用户外部干预。

TPS2540A 自动检测模式还具有更长的断开检测时间,因而能够支持某些特殊的不合规设备。TPS2540/40A/41 电源分配开关适用于可能遭遇大容性负载和短路的应用场合,在单个封装中集成了 73 mΩ N 沟道 MOSFET。当输出负载超过限流阈值时,进入恒流模式。ILIM_SEL 逻辑输入可从两个限流阈值中选择其一,每个阈值均可通过外部电阻单独调节。USB 开关的其他特性包括:去毛刺输出故障报告(FAULT),以及逻辑电平使能端 EN(TPS2540/40A)或输出放电控制端 DSC(TPS2541)。对于 TPS2540/40A,模式 000 用于强制输出放电。
