The grid of FET TT1 is connected with an IO pin Din1 of main control module 42 and nonvolatile memory 43, and drain electrode is connected source ground with an input terminal Dout1 of auxiliary control module 48.Other connected modes that are connected to the connected mode of the FET between main control module 42, nonvolatile memory 43 and auxiliary control module 48 input terminals and FET TT1 are identical.
After consumable chip powers on, the power supply vdd voltage is non-vanishing, the IO pin Din1 of main control module 42 ... Dinn exports high level signal or low level signal under the control of main control module 42, FET TTI ... TTn is conducting or cut-off thereupon, and namely main control module 42 can be to volatile memory 44 output signals and normal operation.At this moment, a plurality of lead-out terminal Qout1 of auxiliary control module 48 ... Qoutn is also by FET T1 ... Tn carries out normal exchanges data to main control module 42 output high level signal or low level signals between main control module 42 and the auxiliary control module 48.
Ink-jet printer stops after volatile memory 44 power supplies, vdd voltage is zero, all lead-out terminal output low level signals of main control module 42, FET TTI ... TTn all ends, the equal output low level signal of all lead-out terminals of auxiliary control module 48, FET T1 ... Tn also ends, and the electric current that capacitor C 2 produces can't flow to main control module 42 and nonvolatile memory 43 from volatile memory 44, auxiliary control module 48.Like this, can effectively prolong the service life of capacitor C 2, also just prolong the service life of consumable chip.
Referring to Figure 10, the detection of power loss unit 49 of present embodiment has a Si Mite reverser 71, two inputs of Si Mite reverser 71 connect respectively the negative electrode of dc source VDD and diode D2, its voltage is VDD1, therefore Si Mite reverser 71 can compare the magnitude of voltage of the dc source VDD that ink-jet printer provides and the height that capacitor C 2 provides supply voltage value, when Si Mite reverser 71 judges that the magnitude of voltage of dc source VDD is lower than capacitor C 2 magnitude of voltage of power vd D1 is provided, judge that namely ink-jet printer stops to power to consumable chip, the signal of output will overturn, namely become low level or become high level from low level from high level, digital logic unit 61 can be judged in the data write non-volatile memory 43 in the volatile memory 44.
When power vd D power down, auxiliary control module 48 control FET Q2 close, and VDD1 stops to nonvolatile memory 43 power supplies.Capacitor C 3 is through resistance R 3 discharges, when VDD2 place voltage be lower than VDD1 place voltage 1/3 the time, auxiliary control module 48 control FET Q2 conductings to nonvolatile memory 43 power supplies, start the operation that data in the second memory cell is written to the first corresponding with it memory cell by capacitor C 2 simultaneously.
After auxiliary control module 48 is written to the first memory cell with the data in the second memory cell, auxiliary control module 48 control FET Q1 conductings, capacitor C 2 by R2 and FET Q1 to the ground discharge, with the Guarantee Status register can not occur when ink-jet printer power supply next time can not zero clearing because of VDD1 place spread of voltage situation.
Certainly, ink-jet printer may be stopped power supply or brownout and cause the erroneous judgement of Si Mite reverser 71 short time, therefore, detection of power loss unit 49 is provided with delay circuit, delay circuit is comprised of resistance R 3, diode D3 and capacitor C 3, and when ink-jet printer was powered to consumable chip, power vd D charged to capacitor C 3 through diode D3, because diode D3 forward conduction resistance is very little, thus C3 be full of the electricity time very short; And stop after the consumable chip power supply at ink-jet printer, diode D3 oppositely ends, capacitor C 3 can only be via resistance R 3 discharges, because of resistance R 3 larger with the time constant setting of capacitor C 3, therefore VDD2 keeps a higher magnitude of voltage at short notice, along with passage of time voltage begins slowly to reduce, Si Mite reverser 71 output signal after after a while just can be overturn.Therefore ink-jet printer stops just to overturn through the output signal of regular hour Si Mite reverser 71 after the consumable chip power supply.In addition, can change the time constant of delay circuit by adjusting capacitor C 3 and the numerical value of resistance R 3.Only have the power down time greater than the time constant of setting, chip just can start transfers to the first memory operation with the second memory data, therefore can greatly save the consumption of C2 storage of electrical energy, preserves for a long time to guarantee the volatile memory data.
