DS1231/S电源监控器给微处理器系统提供了一个有序的关断及自动复位的功能。通过监测输入稳压电源输入端的电压,在即将掉电时产生一个报警信号;也可以用光电耦合置直接与DS1231接口,并且与检测的电压隔离。当V_(cc)超出允差时,将产生RST或RST信号,通过接口电路可以使微处理器停止工作。V_(cc)的允差为5％或10％,可由用户选择。当电源恢复后,微处理器不马上工作,而要等电源稳定后才工作,以保护该系统的非挥发RAM免受破坏。
The DS1231 / S Power Monitor provides the microprocessor system with an organized shutdown and automatic reset function. By monitoring the voltage input of the regulated power supply, an alarm signal is generated about to power off; it can also interface directly with the DS1231 using opto-electronic coupling and is isolated from the sensed voltage. When V_ (cc) out of tolerance, will produce RST or RST signal, through the interface circuit can make the microprocessor stop working. V_ (cc) tolerance of 5% or 10%, by the user to choose. When the power is restored, the microprocessor does not work immediately, and wait until the power is stable to work to protect the system of non-volatile RAM from damage.
