Description
Technical field
The utility model belongs to Charge Management field, particularly relates to a kind of Charge Management equipment based on split circuit.
Background technology
If charge management circuit contains power path circuit and powerpath circuit, just can realize charger and can also power to cell phone system while charging the battery, avoid long-time charging to cause battery repeated charge situation to occur.
The platform of the most main flow of current mobile phone has high pass, MTK etc., are integrated with powerpath circuit in the integrated chip of wherein high-pass platform, but have in integrated chip much with less than function, such as: distinguishing charger and USB charging, this situation causes certain waste to resource.
Integrated powerpath circuit is not also had in the charging IC chip of current MTK platform, more powerpath circuit, charging IC chip are not separated from each other, realize the scheme that charger can also be powered to cell phone system while charging, thus avoid battery to recharge problem.
Utility model content
The utility model provides a kind of Charge Management equipment based on split circuit, comprises electric power management circuit, battery charger, system power supply circuit; Wherein, described electric power management circuit is connected with described battery charger, described system power supply circuit respectively.
Pass through such scheme: achieve to this function of system power supply while charging the battery, thus avoid battery and recharge problem, greatly reduce the life consumption of battery.
By following scheme: power supply unit is managed by field effect transistor and mos and battery charging resistor Rcc charges to described battery charger; Power supply unit turns current comparator Gm to described system power supply circuit supply by reference voltage V REF, battery charging resistor Rcc, system charging resistor Rx, voltage, achieves battery charging, being separated from each other of system power supply.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Figure 1 shows that the structure chart of the Charge Management equipment according to the utility model embodiment 1;
Figure 2 shows that the structure chart of the Charge Management equipment according to the utility model embodiment 2;
Figure 3 shows that the particular circuit configurations figure of the Charge Management equipment according to the utility model embodiment 3.
Embodiment
Hereinafter also describe the utility model in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Figure 1 shows that the structure chart of the Charge Management equipment according to the utility model embodiment 1, comprise electric power management circuit, battery charger, system power supply circuit; Wherein, electric power management circuit is connected with battery charger, system power supply circuit respectively.
Figure 2 shows that the structure chart of the Charge Management equipment according to the utility model embodiment 2, comprise electric power management circuit, battery charger, system power supply circuit, power supply unit; Wherein, electric power management circuit is connected with battery charger, system power supply circuit respectively; Power supply unit is connected with electric power management circuit, battery charger, system power supply circuit respectively.
Power supply unit, for simultaneously to battery charger, system power supply circuit supply.
Electric power management circuit, for controlling power supply unit to battery charger, system power supply circuit supply.
Circuit charging that power supply unit is managed by field effect transistor and mos and battery charging resistor Rcc charges the battery.
Power supply unit turns current comparator Gm to system power supply circuit supply by reference voltage V REF, battery charging resistor Rcc, system charging resistor Rx, voltage.
Power supply unit is the charger switched on power.
Electric power management circuit comprises charging IC chip, power management module PMIC; Wherein, power management module is interconnected with charging IC chip.
Figure 3 shows that the particular circuit configurations figure of the Charge Management equipment according to the utility model embodiment 3, concrete principle is as follows:
As shown in Figure 3: after connecting charger, 5V power supply starts power supply, SYS starts there is voltage.VFB node is used for arranging charge cutoff voltage.
Not only charged but also powering phase: when cell voltage is less than charge cutoff voltage, VSYS is charged the battery by mos pipe and Rcc, while VSYS to system power supply, charging current is determined by ccloop circuit.Ichg＝Vref/Rcc*Rx*Gm。
After battery is full of: when cell voltage reaches cut-ff voltage, stop charging, metal-oxide-semiconductor end, now charge IC still by VSYS to system power supply.
Not during external power supply: after pulling up charger, charging IC does not work, and metal-oxide-semiconductor reverse-conducting, now cell voltage VBAT is powered to SYS by metal-oxide-semiconductor.
After connecting charger, system power supply will one to be powered straight through charger, and the scheme that more existing MTK take, owing to lacking this part circuit of powerpath, system must pass through powered battery, and like this when connecing charger for a long time, battery just has the problem that secondary returning fills, a whole night may fill three or four times repeatedly, greatly reduces the useful life of battery.
Charger charges to battery last on the one hand, and the electricity of on the other hand system consuming cells always, like this will while to charge, power consumption, causes iterative cycles, and increase this split circuit, when there being charger, system just can consume the portion of electrical current that charger provides, not the electricity of consuming cells, the effective like this problem solving battery and repeatedly charge, extends battery.
Pass through such scheme: achieve to this function of system power supply while charging the battery, thus avoid battery and recharge problem, greatly reduce the life consumption of battery.
By following scheme: circuit charging that power supply unit is managed by field effect transistor and mos and battery charging resistor Rcc charges the battery; Power supply unit turns current comparator Gm to system power supply circuit supply by reference voltage V REF, battery charging resistor Rcc, system charging resistor Rx, voltage, achieves battery charging, being separated from each other of system power supply.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
