Circuit for realizing dyking-gasp function based on discrete device

The utility model discloses a circuit for realizing a dyking-gasp function based on a discrete device. Comprising a diode, the positive electrode of the diode is connected to a 12V power supply and is grounded through a first resistor and a second resistor which are sequentially connected in series, an output end pin used for outputting high and low level signals is arranged between the first resistor and the second resistor, and the output end pin is grounded through a first capacitor. The negative electrode of the diode outputs a power supply to an external master controller and is grounded through a sixth capacitor, and the sixth capacitor is an electrolytic capacitor. According to the utility model, the whole device is composed of discrete devices, so that the use of a chip is avoided, the overall cost can be greatly reduced under the condition that the dyking-gasp information transmission can be realized, and the market promotion is facilitated. 本实用新型公开一种基于分立器件实现dying-gasp功能的电路。包括二极管，二极管的正极接入12V供电电源并通过依次
