As further improvement of the utility model, described flash memory device also comprises the current detector, an analog to digital converter and the PMOS switch that are sequentially connected between first, second interface, voltage signal from current detector can be converted to digital signal and export to single-chip controller by described analog to digital converter, and described single-chip controller drives PMOS switch to open according to this digital signal or closes.

As further improvement of the utility model, first, second interface described is identical or different.

As further improvement of the utility model, described single-chip controller can data access between control store and the first or second equipment.

The utility model flash memory device can be connected between first, second equipment, make the first equipment through flash memory device to the second equipment charge, make between first, second equipment, to realize power supply to share, improve power supply to use and the facility shared, production and the manufacture of electron device can be reduced, reduce environmental pollution; Flash memory device has the function of charging Wireless Router concurrently, and multi-functional unification, reduces costs, and improves consumer and uses wish.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model flash memory device and first, second equipment connection.

Embodiment

Refer to shown in Fig. 1, the utility model flash memory device 100 carries out the access of data for connecting one first equipment 200 or one second equipment 200,300, or connect first, second equipment 100,200 simultaneously, access or the charge function of data are provided, first, second equipment 200,300 can be mobile phone, flat board, charger baby, notebook computer, Intelligent wearable equipment etc., is separately installed with power management routines in first, second equipment 200,300.

The utility model flash memory device 100 comprises single-chip controller 10, storer 20, current detector 30, analog to digital converter 40, PMOS switch 50 and first, second interface 60,70.Storer 20 can utilize storage card to replace.First, second interface 60,70 can be identical or different, can be USB interface, Lightning interface or SATA interface etc., in order to be plugged in together with first, second equipment 100,200.

Current detector 30, analog to digital converter 40, PMOS switch 50 are sequentially connected between first interface 60 and the second interface 70, storer 20, analog to digital converter 40 and PMOS switch 50 also link together with single-chip controller 10 respectively, single-chip controller 10 can be received digital signal that analog to digital converter 40 exports also drives PMOS switch 50 closed or open according to the size of this digital signal, and the data access between control store 20 and the first equipment 200 or the second equipment 300.

When the utility model flash memory device 100 is connected with the first equipment 200 or the second equipment 300, single-chip control 10 can run the first equipment 200 or the second equipment 300 pairs of storeies 20 carry out data access.

The utility model also provides a kind of charging method, and it comprises following steps:

1st step, provides above-mentioned flash memory device 100, installs power management routines respectively in first, second equipment 200,300;

2nd step, is plugged in together first, second interface 60,70 and first, second equipment 100,200, and flash memory device 100, first, second equipment 200,300 are set up and electrically conducted, and single-chip controls 10 can differentiate whether connect;

3rd step, the first equipment 200 runs power management routines, proposes power supply requirement to single-chip controller 10;

4th step, the power supply requirement of the first equipment 200 is forwarded to the second equipment 300 by single-chip controller 10; And

5th step, second equipment 300 runs power management routines, promises the power supply requirement of the first equipment 200, the first equipment 200 out-put supply is charged via flash memory device 100 to the first equipment 200, otherwise, forbid that power delivery in the first equipment 200 is to flash memory device 100.
