Embodiment
The invention provides a kind of current control method and device thereof of mobile terminal, detection system output current and charging current when charging, the size of system output current is improved when system output current is less than first threshold or charging current is less than Second Threshold, thus raising charging current, the problem declined to avoid charging current limited by system output current.For making object of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, it is the current control method flow chart of mobile terminal provided by the invention.Current control method provided by the invention comprises:
When S100, charging, charging current detection module detects the size of charging current, the size of current detection module detection system output current.
S200, when power management module judges that system output current is less than first threshold, central processing unit exports corresponding control signal and controls current processing module system output current is amplified to predetermined current scope;
S300, when charging current detection module judges that charging current is less than Second Threshold, if power management module judges that system output current is also less than Second Threshold, central processing unit exports corresponding control signal control current processing module and system output current is amplified to predetermined current scope.
See also Fig. 2, in this step S100, detect charger export the charging current IUSB charged the battery by charging current detection module 100, the electric current being input to anode is the required charging current IUSB detected.System output current IBATT when detecting powered battery by current detection module 200.
Detected system output current IBATT during power supply is input in power management module 300, is judged the size of system output current IBATT and first threshold and Second Threshold by the first electric current comparing unit 301 by current detection module 200.Described first threshold is 2A, and described Second Threshold is 1A.
When the first electric current comparing unit 301 judges that system output current IBATT is less than first threshold 2A, export the first signal (low level signal); When judging that system output current IBATT is less than Second Threshold 1A, export the 3rd signal (low level signal); When judging that system output current IBATT is less than first threshold 2A and is greater than Second Threshold 1A, export the 5th signal (low level signal).
The second electric current comparing unit 101 in charging current detection module 100 compares the size of charging current IUSB and Second Threshold 1A.Described second electric current comparing unit 101 is comparator, the Second Threshold of the electrode input end access 1A of comparator, the negative input access charging current IUSB of comparator.When the second electric current comparing unit 101 judges that charging current IUSB is less than 1A, export secondary signal (high level signal); When judging that charging current IUSB is greater than 1A, export the 4th signal (high level signal).
In described step S200, when judging that system output current IBATT is less than first threshold 2A, first electric current comparing unit 301 exports the first signal (low level signal) to central processing unit 400, and showing needs the system output current IBATT process to during lithium battery power supply.
Central processing unit 400 processes accordingly according to this first signal, that is: memory cell 401 sends the first corresponding command signal to order register unit 402 after identifying the first signal.Order register unit 402 resolves the first command signal, exports corresponding first pulse control signal to current processing module 500.System output current IBATT is amplified to preset range according to this first pulse control signal by the current amplification unit 501 in current processing module 500, i.e. 2A and more than 2A, and can prevent system power IBATT from declining like this affects charging current decline.
It is to be appreciated that when system output current IBATT is less than first threshold 2A, charging current IUSB may influencedly decline, and also may not decline.When system output current IBATT is less than Second Threshold 1A, charging current IUSB must be influenced.Therefore, in step s 200, judging that system output current IBATT is less than 2A with regard to carrying out amplifying the prerequisite (namely implicit Rule of judgment) of process is immediately that charging current IUSB does not decline and is less than 1A.Now charging current IUSB rises or the constant judgement not affecting this step.
Based in charging process, system output current IBATT may cause declining by other factors, be namely less than 2A, and now charging current IUSB may decline or constant.For this reason, whether the present embodiment, in described step S300, is less than Second Threshold 1A for Rule of judgment with charging current IUSB.
When charging current IUSB and system output current IBATT is all less than 1A, amplification system output current IBATT must be needed: namely
When charging current IUSB is less than Second Threshold 1A, the second electric current comparing unit 101 exports secondary signal (high level signal) to central processing unit 400.Judge whether system output current IBATT changes simultaneously.The system output current IBATT of detection is transferred to the first electric current comparing unit 301 by current detection module 200, when first electric current comparing unit 301 judges that system output current IBATT is also less than 1A, the first electric current comparing unit 301 exports the 3rd signal (low level signal) to central processing unit 400.
Now, after the memory cell 401 of central processing unit 400 identifies secondary signal and the 3rd signal, send the second corresponding command signal to order register unit 402.Order register unit 402 resolves the second command signal, exports corresponding second pulse control signal to current processing module 500.System output current IBATT is amplified to 2A and more than 2A according to this second pulse control signal by the current amplification unit 501 in current processing module 500, thus prevents the problem that the decline of system output current IBATT causes charging current IUSB to decline.
When charging current IUSB is less than 1A, when system output current IBATT is greater than 1A and is less than 2A, amplification system output current IBATT must be needed: namely
When charging current IUSB is less than 1A, the second electric current comparing unit 101 exports secondary signal (high level signal) to central processing unit 400.Current detection module 200 detects system output current IBATT now and transfers to the first electric current comparing unit 301 and judges.If when the first electric current comparing unit 301 judges that system output current IBATT is greater than 1A and is less than 2A, the first electric current comparing unit 301 exports the 5th signal (low level signal) to central processing unit 400.
After the memory cell 401 of central processing unit 400 identifies secondary signal and the 5th signal, send the 3rd command signal to order register unit 402.Order register unit 402 resolves the 3rd command signal, exports corresponding 3rd pulse control signal to current processing module 500.The current amplification unit 501 of current processing module 500 inside is according to the 3rd pulse control signal amplification system output current IBATT to 2A and more than 2A.
When charging current IUSB is greater than 1A, when system output current IBATT is greater than 1A and is less than 2A, can stop amplifying: namely
When charging current IUSB is greater than 1A, the second electric current comparing unit 101 exports the 4th signal (low level signal) to central processing unit 400.Current detection module 200 detects system output current IBATT now and transfers to the first electric current comparing unit 301 and judges.If when the first electric current comparing unit 301 judges that system output current IBATT is also greater than 1A and is less than 2A, the first electric current comparing unit 301 exports the 5th signal (low level signal) to central processing unit 400.
After the memory cell 401 of central processing unit 400 identifies the 4th signal and the 5th signal, send the 4th command signal to order register unit 402.Order register unit 402 resolves the 4th signal, exports corresponding stop signal to current processing module 500.The current amplification unit 501 of current processing module 500 inside quits work according to stop signal, namely without the need to amplification system output current IBATT.
It is to be appreciated that described first pulse control signal, the second pulse control signal, the 4th pulse control signal all can amplification system output current IBATT, just amplification degree is different.Amplification degree can make charging current IUSB normal (as being greater than 1A) be as the criterion after amplifying.
