推挽式监控器LM809M3-3.08

推挽式监控器LM809M3-3.08：

LM809M3-3.08微处理器监控电路可用于微处理器和数字系统中的电源监控。在上电、断电和断电的情况下，它们为微处理器提供了复位。功能是监控V。CC提供电压，并在此电压低于工厂程序复位阈值时断言复位信号.复位信号在V之后的240毫秒内保持不变。CC升过门槛。LM 809有一个活动-低复位输出，而LM 810有一个活动-高复位输出。

有七种标准的复位电压选项，适用于监测5V、3.3V和3V的电源电压。由于电源电流只有15A，LM 809/810是便携式设备的理想选择。LM 809/LM 810可在3针SOT-23封装和6引线SON封装中使用。

The LM809/810 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide a reset to the microprocessor during power-up, power-down and brown-out conditions.

The function of the LM809/810 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240ms after VCC rises above the threshold. The LM809 has an active-low RESET output, while the LM810 has an active-high RESET output.

Seven standard reset voltage options are available, suitable for monitoring 5V, 3.3V, and 3V supply voltages.

With a low supply current of only 15μA, the LM809/810 are ideal for use in portable equipment. The LM809/LM810 are available in the 3-pin SOT-23 package and in the 6-Lead SON package.
