摘要（英）：

The invention discloses a multiple-power-supply reset circuit comprising a voltage detecting chip and a first working power supply for supplying power to the voltage detecting chip, wherein the output end of the voltage detecting chip is connected with the base electrode of a triode; a second capacitor is arranged between the voltage detecting chip and the base electrode of the triode; the emitter electrode of the triode is grounded; the collector electrode of the triode is connected with a second working power supply; a third capacitor is arranged between the collector electrode and the emitter electrode of the triode; a third resistor is arranged between the base electrode and the emitter electrode of the triode; one end of the second capacitor, which is far away from the triode, is connected with a second resistor; and the other end of the second resistor is connected with a third resistor. The invention has the advantages of stability in working, low cost and wide range of application.
