单通道的USB电源开关

EUP3548A是一种单信道的电源开关芯片，内部集成了一个75mΩ 的P型MOSFET功率管，该芯片主要应用于USB电源系统。 \n当输出负载过重或者短路时，芯片会进入限流保护模式，此时会拉低限流指示信号OCB。如负载持续超载或短路，芯片内部温度会迅速上升，进入过温保护模式，芯片会切断功率管以防止芯片损毁。 此外，EUP3548A内置了电源欠压保护功能，即当电源电压过低时，芯片也会切断功率管。直至电源电压恢复至正常范围后，才恢复正常工作。 \nOCB是开漏端输出的限流标识引脚，用于标识芯片是否处于过流或者过温保护状态。芯片内置了8ms的延时功能以防止OCB误动作，向主机提供错误的指示信号，例如 • 75mΩ 导通电阻\n• 工作电压: 2.7V to 5.5V\n• 欠压保护功能\n• 11µA 静态电流\n• 1µA 关断电流\n• EUP3548A高电平使能\n• 关断后无反向电流\n• 带延时的开漏端过流指示信号(OCB)\n• 输出关断泄放支路\n• SOT23-5封装\n• RoHS 适用和100% 无铅无鲁;
