200mA/250mA/300mA限流开关

MAX4789–MAX4794系列开关具有内部限流特性，可避免主器件由于负载故障而损坏。这些模拟开关均有低于0.2Ω的导通电阻，工作电压范围为2.3V至5.5V。确保满足200mA、250mA和300mA的限流特性，因此，非常适合SDIO以及负载切换等应用。\n\n 当开关合上并且负载被加到端口时，确保14ms的断开时间是为了保证瞬时电压得到处理。如果此断开时间过后，电流大于受限电流，MAX4789、MAX4791及MAX4793便进入闭锁脱离状态，此模式下开关被断开，同时/FLAG被传给了微处理器。通过再次上电或接通ON引脚，开关能被再次闭合。\n\n MAX4790、M • 确保限流：200mA、250mA、300mA \n• 热关断保护\n• 反向电流保护\n• 0.2Ω导通电阻\n• 确保14ms屏蔽时间\n• /FLAG功能(MAX4789/MAX4791/MAX4793)\n• 80µA电源电流\n• 8µA闭锁电流(MAX4789/MAX4791/MAX4793) \n• 0.01µA关断电流\n• 供电电源范围为2.3V至5.5V\n• 欠压闭锁\n• 快速限流响应时间(5µs) \n• 提供TDFN和SOT23/SOT143封装;
