Description of drawings
Fig. 1 is the circuit diagram of the novel power supply control and management circuit that provides of the utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below the utility model is further described with reference to the accompanying drawing embodiment that develops simultaneously.
The circuit diagram of novel power supply control and management circuit as shown in Figure 1.Comprise three delay circuits, first delay circuit, second delay circuit, the 3rd delay circuit, each delay circuit is made up of at least one resistance and at least one electric capacity, and its delay time is by the value decision of resistance R and capacitor C, described delay time τ=R*C.By adjusting the RC value, just can adjust delay time.What be connected with delay circuit is the field of electric force effect transistor of output control circuit, adopts N type metal-oxide-semiconductor in this enforcement.Correspond to first control circuit Q1 respectively, second control circuit Q2, the 3rd control circuit Q3.Supply voltage U is as power supply, the second road power supply U2, and Third Road power supply U3, the four tunnel circuit U 4 is through the output of the power supply after the control.
Please continue referring to Fig. 1, comprise a power supply, at least one delay circuit, at least one output control circuit, described delay circuit comprises at least one resistance and at least one electric capacity, and described resistance is connected with capacitances in series; Described output control circuit is a N type metal-oxide-semiconductor, the output of the resistance of described delay circuit is connected with the grid of output control circuit, the other end ground connection of the electric capacity of described delay circuit, the other end of the resistance of described delay circuit and the source electrode of output control circuit are connected in parallel on the output of an out-put supply, on the end of the resistance of the delay circuit of the drain electrode of described output control circuit connection load and next out-put supply.
After supply voltage U output, first via power supply U1 externally produces output immediately, behind the delay time R1*C1 of first delay circuit of forming through first resistance R 1 and first capacitor C 1, capacitor C 1 charging is saturated in first delay circuit, when grid among the first control circuit Q1 and the voltage between the source electrode are greater than or equal to the cut-in voltage of first control circuit Q1, first control circuit Q1 opens, and the second road power supply U2 externally produces output; Behind the delay time R2C2 through second delay circuit, in like manner, second control circuit Q2 opens again, and Third Road power supply U3 externally produces output; After passing through the delay time R3C3 of Third Road power supply again, in like manner, the 3rd control circuit Q3 opens, and the four tunnel circuit U 4 externally produces output.
Like this, only need one road power supply U, just can produce other three-way power respectively with first via power supply U1 interval R1C1, R1C1+R2C2, R1C1+R2C2+R3C3 duration.
As long as the utility model is one road power supply, by resistance capacitance delay circuit and N type metal-oxide-semiconductor just can be controlled and managing electrical power is exported cheaply order and blanking time.Save the resource of software systems, also improved reliability.With regard to circuit itself, this circuit is also extremely simple, with low cost.
Should be understood that application of the present utility model is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion, for example, at different application systems, the time interval is different, just can as long as adjust the value of R and C.If the more power requirement of multichannel is arranged, only need increase the way that same circuits just can increase out-put supply according to same principle.All these improvement and conversion all should belong to the protection range of the utility model claims.
