ADM6348, 超低功耗、3引脚SOT-23微处理器复位电路，低电平有效开漏输出，1 μA电源电流

Wed, 11 Nov 2009 09:00:19 GMT

ADM6326/ADM6328/ADM6346/ADM6348均为超低功耗微处理器监控电路，适合监控微处理器和电信应用中的电源。超低电源电流使这些器件非常适合低功耗便携式设备使用。

这些器件在上电、关断和掉电情况下提供复位输出。上电时，内部定时器使RESET （复位）保持置位状态至少100 ms。这样，微处理器会保持复位状态，直到电源达到稳定状态为止。

ADM6326和ADM6346提供低电平有效推挽复位输出。ADM6328和ADM6348提供低电平有效开漏复位输出，但需要使用外部上拉电阻。即使V_CC低至1 V，复位输出仍然可以工作。复位比较器内置抗突波特性，使器件不受V_CC的快速瞬变影响。
