Fig. 2 is the structural representation the utlity model has in embodiment of cell apparatus of zero stand-by power consumption.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In the utlity model has the cell apparatus embodiment of zero stand-by power consumption, the structural representation of this cell apparatus as shown in Figure 2.In Fig. 2, this cell apparatus with zero stand-by power consumption comprises power supply BAT1, MCU, load M1, load switch Q1 and switching circuit, one end of power supply BAT1 is connected with one end of switching circuit, the other end of switching circuit is connected with one end of load M1 with the power end VCC of MCU respectively, the other end of load M1 is connected with one end of load switch Q1, the other end of load switch Q1 is connected with an I/O mouth of MCU, another I/O mouth of MCU is connected with the another end of switching circuit, by open control switch circuit to another I/O mouth input signal of MCU, connect so that MCU and load M1 obtain electric work, and cut off switching circuit so that cell apparatus enters holding state by another I/O mouth of MCU.In the present embodiment, load switch Q1 is metal-oxide-semiconductor, and the drain electrode of metal-oxide-semiconductor is connected with the other end of load M1, and the grid of metal-oxide-semiconductor is connected with an I/O mouth of MCU, the source ground of metal-oxide-semiconductor.
In the present embodiment, switching circuit comprises switching tube Q2, the first resistance R 1 and the second resistance R 2, one end of switching tube Q2 is connected with one end of the first resistance R 1 with the positive pole of power supply BAT1 respectively, the other end of switching tube Q2 is connected with one end of the second resistance R 2 with the other end of the first resistance R 1 respectively, the another end of switching tube Q2 is connected with one end of load M1 with the power end VCC of MCU respectively, and the other end of the second resistance R 2 is connected with another I/O mouth of MCU.
In the present embodiment, switching tube Q2 is triode Q2, the emitter of triode Q2 is connected with one end of the first resistance R 1 with the positive pole of power supply BAT1 respectively, the base stage of triode Q2 is connected with one end of the second resistance R 2 with the other end of the first resistance R 1 respectively, and the collector electrode of triode Q2 is connected with one end of load M1 with the power end VCC of MCU respectively.Certainly, in other embodiments, switching tube Q2 can be also metal-oxide-semiconductor.
In the present embodiment, pumping signal is push button signalling or vibration signal or load signal etc.When user uses, at another I/O mouth of MCU or the other end of the second resistance, add a pumping signal, when pumping signal is push button signalling, this pumping signal is used function key and is produced, now triode Q2 is opened, and MCU and load M1 is obtained electric, then maintains triode Q2 conducting by another I/O mouth of MCU, make MCU and load M1 always electric, cell apparatus is in normal operating conditions.When user does not use, another I/O mouth by MCU controls to close triode Q2, make cell apparatus get back to holding state, now standby current equals the leakage current between the collector and emitter of triode Q2, during triode Q2 cut-off, leakage current <0.1uA between collector and emitter, thus stand-by power consumption <0.1uA, no better than zero.Because stand-by power consumption can be accomplished <0.1uA, little more a lot of than 50 ~ 500uA on the market, so battery product is placed 1-2, then takes out while using, or full electricity, can directly use.So when not worrying wanting using, discovery there is not electricity and can not immediately uses, even battery damages and cannot use; Because stand-by power consumption is large, battery is easy to no electricity, do not have electric battery to continue placement and can greatly reduce battery, and cell apparatus stand-by power consumption in the present embodiment is little, so it can extend battery.
In a word, in the present embodiment, with triode Q2 or metal-oxide-semiconductor, cut off general supply and reduce stand-by power consumption, during work, with MCU, maintain power supply, can normally work again.So its stand-by power consumption is little, extending battery life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
