Technical field
This utility model relates to a kind of single chip circuit, specifically a kind of Intelligent Single-Chip Based reset control circuit.
Background technology
The reset circuit of prior art is generally connected by two electric capacity and a resistance and forms, the reset electricity of said structure
Road has the disadvantage that owing to this reset circuit does not has reset delay, i.e. discharges complete by time delay by the electric charge in electric capacity,
If the most not discharging complete by the electric charge in electric capacity, it will necessarily affect the reset of next time, thus affects this reset circuit
Functional reliability.
Utility model content
The purpose of this utility model is to provide a kind of Intelligent Single-Chip Based reset control circuit, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of Intelligent Single-Chip Based reset control circuit, including resistance R1, electric capacity C1, inductance L, audion VT1 and diode
D1, described inductance L one end connects power supply VCC, and the inductance L other end connects electric capacity C1, diode D1 negative pole and resistance R3 respectively, electricity
The resistance R3 other end connects diode D1 positive pole, resistance R4, electric capacity C2 and audion VT1 colelctor electrode respectively, and the resistance R4 other end is even
Connecing reset RESET foot, electric capacity C2 other end connecting triode VT1 emitter stage ground connection, audion VT1 base stage connects resistance R2,
The resistance R2 other end connects diode D2 negative pole, resistance R1, resistance R5 and the electric capacity C1 other end respectively, and the resistance R5 other end connects
Signal Vi, the resistance R1 other end connects diode D2 positive pole ground connection.
As this utility model further scheme: described power supply VCC voltage is 5V.
Compared with prior art, the beneficial effects of the utility model are: this utility model Intelligent Single-Chip Based resets and controls electricity
Road, it is adaptable to various Single Chip Microcomputer (SCM) system, after power-off, on RESET foot, electric current is directly output to ground from D1 rather than flows through R3, plays
Accelerating the effect of electric discharge, stability is high.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of Intelligent Single-Chip Based reset control circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of Intelligent Single-Chip Based reset control circuit, including resistance R1, electricity
Holding C1, inductance L, audion VT1 and diode D1, described inductance L one end connects power supply VCC, and the inductance L other end connects electricity respectively
Holding C1, diode D1 negative pole and resistance R3, the resistance R3 other end connects diode D1 positive pole, resistance R4, electric capacity C2 and three respectively
Pole pipe VT1 colelctor electrode, the resistance R4 other end connects reset RESET foot, and electric capacity C2 other end connecting triode VT1 emitter stage also connects
Ground, audion VT1 base stage connects resistance R2, and the resistance R2 other end connects diode D2 negative pole, resistance R1, resistance R5 and electricity respectively
Holding the C1 other end, the resistance R5 other end connects signal Vi, and the resistance R1 other end connects diode D2 positive pole ground connection；Described power supply
VCC voltage is 5V.
Operation principle of the present utility model is: refer to Fig. 1, and when powering on, electric capacity C1 is inoperative, and VT1 is led by power supply VCC
Logical, thus RESET is dragged down output；When a period of time etc. to be initiated after, C1 be full of cut off unidirectional current, VT1 end,
RESET is output as height, and i.e. reset complete starting working.It is to be noted that the size of C1 directly determines the discharge and recharge time, also
Time span the most from low to high.If the shortest, during voltage instability, when resetting upon complete starting working, there will be deadlock phenomenon,
So suitably selecting bulky capacitor, after allowing power supply have time enough stable, the complete work again that reset is effectively reduced deadlock.Two poles
The effect of pipe D1, is to accelerate the electric discharge of RESET foot after power-off, in order to avoid forward/backward operation influences each other when high-speed switch machine, former
Reason is powered off electric current on rear RESET foot and is directly output to ground from D1 rather than flows through R3, because diode has pressure drop, so rising
To the effect accelerating electric discharge.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
