On the other hand, when electronic installation 200 shuts down, described multiple status signal can be maintained second electrical level (such as: logical zero) by embedded controller 222.In addition, when described multiple status signal maintains second electrical level (such as: logical zero), on-off circuit 221 will provide the setting signal with the first level (such as: logical one), using as power-off signal SCT2.
For example, as shown in Figure 3, when electronic installation 200 performs shutdown, described multiple status signals, such as: dormant control signal slp-s3#, dormant control signal slp-s4#, wake control signal wake# and specific control signal GPO etc. up, second electrical level (such as: logical zero) will all be maintained.Thus, interrupteur SW 31 ~ SW34 not conductings, and then cause the level of setting signal S31 to be pulled up to voltage V3.That is, generation is had the setting signal S31 of the first level (such as: logical one) by on-off circuit 221 now, and it will be regarded as power-off signal SCT2.
Continue referring to Fig. 2, the power supply signal SON2 produced for on-off circuit 221 and power-off signal SCT2, switch element 230 will according to power supply signal SON2 conducting first link TM21 and the second link TM22, and then cause power-supply unit 210 can receive power ps 2 constantly.In addition, switch element 230 according to power-off signal SCT2 open circuit first link TM21 and the second link TM22, and then can cut off the power ps 1 being supplied to electronic installation 200.
For example, Fig. 4 is the circuit diagram of the switch element according to one embodiment of the invention.Switch element 230 comprises relay 410, control circuit 420 and interrupteur SW 4.Wherein, relay 410 has the first link TM21 and the second link TM22.Control circuit 420 connects relay 410.In addition, interrupteur SW 4 connection control circuit 420 and the on-off circuit 221 in control module 220 respectively.
Further, control circuit 420 comprises diode D4, N-channel transistor MN4, resistance R41 and R42 and electric capacity C4.In addition, relay 410 comprises coil L4, common joint CO1, normally closed contact NC1 and normal opened contact N01.In connection, common joint CO1 and the normal opened contact N01 of relay 410 are connected the first link TM21 and the second link TM22 of relay 410, respectively to control the conducting state of the first link TM21 and the second link TM22 thus.
Moreover first power end of the coil L4 of relay 410 connects power-supply unit 210, with receiving system voltage VS1, and the second source end of the coil L4 of relay 410 connects the drain electrode of N-channel transistor MN4.First power end of the negative electrode connecting coil L4 of diode D4, and the second source end of the anode connecting coil L4 of diode D4.First power end of resistance R41 connects the source electrode of N-channel transistor MN4, and the second source end of resistance R41 connects earth terminal.First power end of electric capacity C4 connects power-supply unit 210, and the second source end of electric capacity C4 connects the grid of N-channel transistor MN4.First power end of resistance R42 connects the second source end of electric capacity C4, and the second source end of resistance R42 connects earth terminal.First power end of interrupteur SW 4 connects first power end of electric capacity C4, and the second source end of interrupteur SW 4 connects the second source end of electric capacity C4.
In integrated operation, electric capacity C4, resistance R41 and resistance R42 are the bias point determining N-channel transistor MN4.In addition, N-channel transistor MN4 is in order to drive coil L4, and diode D4 is the discharge path providing coil L4.At this, when switch element 230 receives power supply signal SON2, interrupteur SW 4 by conducting, and then causes the voltage being positioned at node N4 to be pulled up to system voltage VS21.Along with the lifting of the voltage of node N4, N-channel transistor MN4 is by conducting, and then drive coil L4, and causes the common joint CO1 of relay 410 to be connected to normal opened contact N01.That is, when switch element 230 receives power supply signal SON2, the first link TM21 of switch element 230 and the second link TM22 is by mutual conduction.
On the other hand, when switch element 230 receives power-off signal SCT2, interrupteur SW 4 is by not conducting.Now, system voltage VS21 charges starting to electric capacity C4, and causes the voltage being positioned at node N4 to start toward declining.Along with the decline of the voltage of node N4, N-channel transistor MN4 cannot conducting, and then causes the common joint CO1 of relay 410 to be connected to normally closed contact NC1.In other words, when switch element 230 receives power-off signal SCT2, the first link TM21 and the second link TM22 of switch element 230 cannot mutual conduction.
It is worth mentioning that, before control module 220 is not yet by driving, switch element 230 to receive power supply signal SON2 and power-off signal SCT2.Therefore, electronic installation 200 is at the initial stage of start, the delay mechanism that switch element 230 will utilize electric capacity C4 and resistance R42 to be formed, impels the conducting that N-channel transistor MN4 remains of short duration, and then causes the first link TM21 and the second link TM22 to be electrical connected momently.Thus, power-supply unit 210 control module 220 complete by driving before, power ps 2 can be received constantly.
Why first link TM21 of switch element 230 and the second link TM22 can maintain of short duration being electrical connected at the initial stage of starting shooting, chief reason is, under direct current transient response, the electric capacity C4 receiving system voltage VS2 is at the beginning regarded as short circuit, therefore, at the initial stage that electronic installation 200 is started shooting, the voltage being positioned at node N4 maintains system voltage VS21.In addition, electric capacity C4 just can charge to system voltage VS2 after must waiting for a time delay.That is, the voltage being positioned at node N4 can in time delay gradually toward declining.
Wherein, the size of time delay is the resistance value depending on electric capacity C4 and resistance R42.Therefore, the adjustment of the resistance value of electric capacity C4 and resistance R42 can be utilized, is set greater than the driving time of control module 220 time delay.Thus, before control module 220 is not yet by driving, by the transient response of electric capacity C4, interrupteur SW 4 will maintain the state of conducting within time delay, and then cause the first link TM21 of switch element 230 and the second link TM22 to maintain of short duration being electrical connected at the initial stage of starting shooting.
In sum, under electronic installation 200 is in open state, the first link TM21 of switch element 230 and the second link TM22, by mutual conduction, can provide system voltage VS21 ~ VS23 constantly to cause power-supply unit 210.Otherwise when electronic installation 200 shuts down, the first link TM21 of switch element 230 and the second link TM22 by open circuit, and then cuts off the power supply being supplied to electronic installation 200.
Thus, the electronic installation 200 of the present embodiment can reach the effect of zero power consumption in the power-offstate, and then improve province's electrical efficiency of system.In addition, because electronic installation 200 is not power consumption in the power-offstate, therefore in the process of start, the embedded controller 222 of the present embodiment performs boot program when first time receives system voltage VS22.That is, when embedded controller 222 is driven by system voltage VS22, embedded controller 222 will perform boot program.
