Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the circuit diagram of a kind of preferred embodiment of electricity-saving mode power management system of the present invention.
Embodiment
A specific embodiment of electricity-saving mode power management system of the present invention and method is described below in conjunction with Fig. 1; as shown in Figure 1 in the electricity-saving mode power management system; TR1 is the PNP triode; TR2 is the NPN triode; KEY is a button; C1 is a filter capacitor; D1 is the first protection diode; D2 is the second protection diode; 5V is a direct supply; VDD is the load circuit power end; R3 is first current-limiting resistance; R5 is second current-limiting resistance; R2 is the loop resistance of TR1; R4 is the stake resistance of TR2 base stage pipe, and R1 is a pull-up resistor, and I/O1 is a control port; I/O2 is a detection port, and load circuit is a single chip circuit.
When triggering button KEY, moment by diode D1 and resistance R 3 ground connection, makes the TR1 conducting with the base stage of TR1,5V voltage is delivered to the rear end supplies with Single Chip Microcomputer (SCM) system and use, because TR1 has individual tube voltage drop, just becomes VDD to the rear end and (is approximately 4.7V～4.9V);
Just start working when Single Chip Microcomputer (SCM) system receives power vd D, make I/O1 mouth output high level simultaneously, make the TR2 conducting, make TR1 continue conducting by resistance R 3 and TR2 ground connection the base stage of TR1; When button KEY lifted, TR1 conducting by R3 and TR2 guaranteed the power supply of rear end Single Chip Microcomputer (SCM) system;
When not needing Single Chip Microcomputer (SCM) system work,, make the I/O1 output low level via Single Chip Microcomputer (SCM) program control, TR2 is turn-offed TR1, thereby cut off the power supply (being that VDD becomes 0V) of Single Chip Microcomputer (SCM) system, thereby avoid single-chip microcomputer power consumption, reach the effect of saves energy owing to standby.
The effect of diode D1 is, under the single-chip microcomputer duty, prevents from TR1 to be turn-offed and system can not be worked when I/O2 output high level; The effect of diode D2 is to prevent that TR1 from misleading because, were it not for D2, the base stage of TR1 by resistance R 3 and D1 directly and I/O2 join and continue conducting, make keys deactivation;
When the following time of state that Single Chip Microcomputer (SCM) system is being worked, when triggering button KEY once more, can detect button by I/O2 through D1, thereby carry out other functions of Single Chip Microcomputer (SCM) system, for example trigger one-touch and carry out the function of a defined, trigger the secondary button and carry out the function of secondary defined ... Deng, single-chip microcomputer can be discerned and trigger button several times;
Resistance R 1 is a current-limiting resistance, prevents when button, and VDD is the short circuit by D2 ground connection directly; Resistance R 4 is to prevent that TR2 from misleading, because single-chip microcomputer is in power up, the output state of I/O is indefinite, might export high level false triggering TR2, so force to drag down by R4; Resistance R 3 is identical with the R5 effect, is current-limiting resistance all; Resistance R 2 is that current return is provided when TR2 needs conducting.
