The utility model is by detecting cell voltage under charged state, thereby and in the time that cell voltage reaches certain value, send starting-up signal to system module triggering mobile terminals start, realized battery and inserted the effect of charger charging Auto Power On in the situation that being discharged completely.
Accompanying drawing explanation
Fig. 1 is the embodiment schematic diagram of a kind of mobile terminal of the utility model;
Fig. 2 is that the starting-up signal receiving-end voltage of system module under mobile terminal charged state changes schematic diagram.
Embodiment
In order to make relevant technical staff in the field understand better the technical solution of the utility model, below in conjunction with the accompanying drawing of the utility model execution mode, technical scheme in the utility model execution mode is clearly and completely described, obviously, described execution mode is only the utility model part execution mode, rather than whole execution modes.
As shown in Figure 1, a kind of mobile terminal comprises system module 10, power management module 11, battery module 12, battery voltage detection module 13 and manual starting module S1.
The charging input end 113 of described power management module 11 is connected with charger under charged state, the battery connectivity port 111 of described power management module 11 is connected with battery module 12 is anodal, the system voltage output 112 of power management module 11 is connected with the power input 102 of system module 10, for system module 10 provides system voltage power supply.In the time that mobile terminal charges, charging input end 113 connecting chargers of described power management module 11, power management module 11 charges for battery module 12 on the one hand, powers on the other hand for system module 10; In the time that mobile terminal does not charge, described battery module 12 is powered for system module 10 by power management module 11.
The voltage input end 131 of described battery voltage detection module 13 is connected with the positive pole of battery module 12, the signal output part 132 of described battery voltage detection module 13 is connected with the first end of the starting-up signal receiving terminal 101 of system module 10 and described resistance R 1, and the second end of described resistance R 1 is connected with the system voltage output 112 of power management module 11.
Described battery voltage detection module 13 in the time detecting that cell voltage exceedes threshold voltage described in signal output part 132 send starting-up signal to system module 10.Described battery voltage detection module 13 is that threshold voltage is the power supply detection chip of 3.2V.
When under the state that mobile phone is discharged completely, connect charger charging, battery voltage detection module 13 detects the voltage of battery module 12, in the time that the voltage of battery module 12 does not reach threshold voltage, the signal output part 132 of battery voltage detection module 13 does not have signal output, and the size of the voltage of the starting-up signal receiving terminal 101 of system module 10 equals the system voltage of the system voltage output output 112 of power management module 11; When the voltage of battery module 12 reaches threshold voltage, the signal output part 132 of battery voltage detection module 13 is exported a low level signal, and now the starting-up signal receiving terminal 101 of system module 10 receives low level signal, the start of triggering system module.Described low level signal can be the 0V signal of 200ms.
