MAX6346

3引脚、SC70/SOT封装、超低功耗的微处理器复位电路; • 超低电源电流：1µA（最大值）(MAX6326/MAX6327/MAX6328)\n\n• 对2.5V、3V、3.3V和5V电源电压进行精密监控\n\n• 复位阈值范围：2.2V至4.63V\n\n• 可在整个温度范围内完全符合规格\n\n• 上电复位脉冲宽度：100ms（最小值）\n\n• 低成本\n\n• 提供三个版本：推挽低电平有效RESET、推挽RESET和开漏低电平有效RESET\n\n• 电源瞬变抗扰度\n\n• 无需外部元件\n\n• 3引脚SC70/SOT23封装\n\n• 与MAX803/MAX809/MAX810引脚兼容;

MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348微处理器(µP)监控电路可监控µP和数字系统中的电源。当与2.5V、3V、3.3V和5V供电电路一起使用时，这些器件无需外部元件，也不用进行调整，可实现非常可靠的低成本电路。\n\n 这些电路执行单一功能：每当VCC电源电压下降到预设阈值以下时，它们都会将复位信号置位，并在VCC上升到复位阈值以上后将该信号保持置位状态至少100ms。这些器件之间只有输出有所不同。MAX6326/MAX6346（推挽）和MAX6328/MAX6348（开漏）提供低电平有效复位输出。MAX6327/MAX6347提供高电平有效推挽复位输出。VCC低至1V时，所有这些器件都能处于正确的状态。复位比较器旨在忽略VCC的快速瞬变。复位阈值可在2.2V和4.63V之间进行工厂调整，增量约为100mV。提供21个标准版本。有关非标准版本的供货情况，请联系工厂。\n\n 这些器件具有超低电源电流（MAX6326/MAX6327/MAX6328最大为1µA），因此非常适合便携式设备应用。所有六款器件均采用节省空间的SOT23和SC70封装。\n\n  \n\n
