Embodiment
Main thought of the present invention is to utilize and is integrated in charging circuit in communication module for intelligent mobile terminal and charges, and this mobile terminal is comprise the intelligent terminal that mobile phone, navigator etc. adopt application processor and communication module framework.
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
According to embodiments of the invention, provide a kind of mobile terminal.
Fig. 2 is the structured flowchart of the mobile terminal of the embodiment of the present invention, this mobile terminal adopts the framework based on application processor and communication module (AP+Modem), as shown in Figure 2, this mobile terminal comprises: charging port 10, application processor 20, communication module 30 and battery module 40.
Wherein, application processor 20 is connected with communication module 30.Communication module 30 inside is integrated with charging circuit 32, charging circuit 32 is connected with battery module 40 with charging port 10 respectively, charging circuit 32 is under the control of application processor 20 and communication module 30, and for battery module 40 is powered, battery module 40 is powered for application processor 20 and communication module 30.According to this embodiment, by charging circuit integrated in use communication module for mobile terminal charges, mobile terminal need not arrange charging circuit separately again, reduces hardware cost and PCB fabric swatch area.
Fig. 3 is the structured flowchart of the mobile terminal of one embodiment of the invention, and on the basis of Fig. 2, as shown in Figure 3, application processor 20 comprises: detection module 22 and identification module 24; Communication module 30 also comprises: configuration module 34 and control module 36.
Whether wherein, detection module 22 is connected with charging port 10, have charge power supply to access for detecting charging port 10.Identification module 24 is connected with detection module 22 with charging port 10, for when detection module 22 has detected that charge power supply accesses, identifies charge type.In actual applications, identification module 24 is connected with charging port 10 by usb signal, and implements the function of charge type identification by usb signal.
Need explanation, above-mentioned charge type carries out dividing according to the electric current of the charge power supply of access charging port, comprise: use charger to carry out charging and use USB to charge, wherein, use USB carries out charging and namely uses USB Host (master) equipment to charge.
Continue with reference to figure 3, configuration module 34 is connected with identification module 24, configures corresponding charging current for the charge type identified according to identification module 24.Control module 36 is connected with configuration module 34, and the charging current for configuring according to configuration module 34 controls charging circuit 32 and charges for battery module 40.
Before battery module 40 charging complete, battery module 40 is all one direction shut-off, i.e. only input current and not output current.At this moment, charging circuit 32 is needed to power for mobile terminal.Particularly, as shown in Figure 2, charging circuit 32 is connected with communication module 30 with application processor 20 respectively, and when detection module 22 has detected that charge power supply accesses, on the one hand, charging circuit 32 charges for battery module 40; On the other hand, charging circuit 32 is directly powered for application processor 20 and communication module 30, ensure that mobile terminal can normally use.
Because its charging current of different charge type is different, so require that configuration module 34 configures corresponding charging current according to charge type.Control module 36 controls charging circuit 32 according to the charging current that configuration module 34 configures and charges for battery module 40.Particularly, current according to battery module voltage control enters the corresponding charging stage.If present battery module voltage is lower than the first voltage (such as 3.2v), be protection battery module, then entering precharge mode, take small area analysis as charging battery module; If present battery module voltage is higher than the first voltage but lower than the second voltage (4.2v), then enter constant current charging mode, this demands charger charges with larger electric current; If present battery module voltage is higher than the second voltage, then enter constant voltage charge pattern, in such a mode, voltage remains unchanged, and charged electrical fails to be convened for lack of a quorum and progressively reduces, after charging current is reduced to certain numerical value, stop charging.
