具有低电平有效推挽输出的微处理器监控电路，采用3引脚SOT-23和SC70封装

ADM809监控电路用于监控微处理器系统中的电源电压，可在上电、关断和掉电情况下提供复位输出。上电时，内部定时器使复位保持置位状态240 ms。这样，微处理器会保持复位状态，直到电源达到稳定状态。即使VCC低至1 V，/RESET输出仍然可以工作。ADM809可提供低电平有效复位信号/RESET，还有一个推挽输出级。\n\n 共提供7种复位阈值选项。复位比较器具有内置抗突波特性，能够不受VCC的快速瞬变影响。\n\n ADM809提供3引脚SOT-23和SC70两种封装，功耗仅为17 µA，适合低功耗便携式设备使用。 • 可在整个温度范围内提供额定性能 \n\n• 低功耗(17 µA)\n\n• 精密电压监控器：2.5 V、3 V、3.3 V、5 V选项;
