具有电缆补偿功能的 USB 汽车类充电端口控制器和 3A 电源开关

TPS2549 器件是一款 USB 充电端口控制器和电源开关，其带有可控制上行电源的电流感测输出。该器件可使 USB 端口电压维持在 5V 水平，即使 充电电流过大也依然有效。这对于 USB 电缆较长的系统而言至关重要，因为该系统在对便携式设备进行快速充电的过程中会产生大幅压降。 TP2549 47mΩ 电源开关具有两个可选的可编程电流限值，可通过在相邻端口承载高负载时提供较低电流限值来支持端口电源管理。这对于具有多个端口并且上行电源无法同时为所有端口提供满载电流的系统而言至关重要。 DCP_Auto 方案通过检测并选择合适的 D+ 和 D– 设定与所连设备进行通信，以便在满载电流条件下完成快 • 4.5V 至 6.5V 的工作范围\n• 最大连续开关电流达 3A\n• 充电下行端口 (CDP) 模式符合 USB 电池充电规范 1.2\n• 短路模式符合 BC1.2 和 YD/T 1591-2009\n• 1.2V 模式\n• 面向系统更新的 D+ 和 D– 客户端模式\n• D+ 和 D– ±8kV 接触放电和 ±15kV 空气放电 ESD 额定值 (IEC 61000-4-2)\n• 运行结温范围：-40°C 至 125°C\n• 16 引脚 3mm x 3mm 四方扁平无引线 (QFN) 封装;
