And one second endpoint 114b, which is coupled to by first light emitting device 102a.Wherein, when this can
So that when central processing unit 104c normal operation, central processing unit 104c can not be indicated for the undertension of rechargeable battery 106
Driver 104b goes to control shining for first light emitting device and second light emitting device 102a, 102b；In this way, if nothing
If the auxiliary device 110 of the present embodiment, user will be unable to learn the current state of the rechargeable battery.According to the present invention,
When the undertension of the rechargeable battery 106, central processing unit 104c because can not normal operation and can not be defeated
The disable signal out.And the access device 114 is in enable (enabled) state because being not received by the disable signal, and provides
One current path makes the first light emitting device 102a shine.Due to this current path, charge power supply can provide electric current from the power supply
Receiving end 108 makes first light emitting device by power supply receiving end 112, the first light emitting device 102a and access device 114
102a, to indicate that user's rechargeable battery is in charged state.
With the process of charging, the voltage of the rechargeable battery 106 can also rise.When the voltage of the rechargeable battery 106
When being enough to make the normal operation of central processing unit 104c, central processing unit 104c also sends out the disable signal again keeps this logical
Road device 114 returns to forbidden energy (disabling) state, and driver 104b also receives the finger from central processing unit 104c at this time
Show, and controls the first light emitting device 102a and second light emitting device 102b according to the grade instructions.
Fig. 2 is 200 schematic diagram of circuit according to an electronic device of the embodiment of the present invention.In this embodiment, function
Object identical with Fig. 1 is operated with symbology identical with Fig. 1, detail explanation is as described in Figure 1.In this embodiment,
It further include a third light emitting device 102c other than the first light emitting device 102a, the second light emitting device 102b.This first to
Three light emitting device 102a~102c, herein respectively three light emitting diode L0~L2.The wherein equal light emitting diodes L0~L2
Be connected to the rechargeable battery 106 by diode D2, and can the power supply provided by rechargeable battery 106 drive.In addition,
Three light emitting diode L0~L2 can be the device being packaged together, and can also be an other component, also or with other
Configuration mode encapsulation.
Drive dynamic control device 104 includes output end a 104a, a driver 104b and a central processing unit 104c.Wherein drive
The pin VDD of dynamic device 104b is connected to rechargeable battery 106 to use power supply provided by the rechargeable battery 106.Pin VSS
It is grounded with EPAD.And pin SDA and SCL are connected to central processing unit 104c to receive the instruction from central processing unit 104c and believe
Number (data-signal and clock signal).Driver 104b indication signal according to received by pin SDA and SDL and control pin
The output level and/or electric current of LED0~LED2.Central processing unit 104c receives electricity provided by the rechargeable battery 106
Source, and when central processing unit 104c is working properly, a disable signal S is exported by output end 104adb。
In this embodiment, which includes: a power supply receiving end 112, is coupled to the charge node 108 simultaneously
And the anode of light emitting diode L2 is connected with diode D1 by resistor R1；One resistor R2, an access device
114, there is a first end point 114a, couple output end 104a and one second endpoint 114b, pass through the light emitting diode
L2, diode D1 and resistor R1 and be connected to the power supply receiving end 108.And access device 114 further includes the oxidation of two N-type metals
Object semiconductor field effect transistor (N Type Metal-Oxide-Semiconductor Field-Effect
Transistor, hereinafter referred to as NMOS transistor) a Q1 and Q2 and resistor R3, as shown in Figure 2.And NMOS transistor Q1 with
Working condition of the Q2 under various source conditions is described as follows.
Consider that the power supply of the rechargeable battery 106 is not enough to drive dynamic control device 104 and connects from the charge node 108 first
Receive the case where charge power supply is to be charged.In the case, central processing unit 104c can not normal operation without exporting
End 104a exports disable signal Sdb, therefore the grid input of NMOS transistor Q2 is low level, and the leakage of NMOS transistor Q2
It is open circuit between pole and source level.NMOS transistor Q1 at this time, due to its grid by power supply receiving end 112 and resistor R2 receive come
It is connected from the charge power supply of the charge node 108 and (provides a current path).Therefore, self-charging node 108, power supply receiving end
112, diode D1, light emitting diode L2, the second endpoint 114b, NMOS transistor Q1 to ground connection be an access, therefore shine two
Pole pipe L2 shines.In this embodiment, the luminous power supply storage that can be represented inside the rechargeable battery 106 of light emitting diode L2
It is too low and be in the state being electrically charged.
Then consider that the charge node 108 receives the voltage of charge power supply, but the power supply of rechargeable battery 106 is enough to drive control
The case where device 104 processed.In the case, central processing unit is working properly and exports disable signal S in output end 104adb
NMOS transistor Q2 is connected in (high level).At this point, the voltage of the grid of NMOS transistor Q1 is low level, therefore NMOS crystal
Pipe Q1 is open circuit.Therefore the second endpoint 114b, NMOS Q1 are between being grounded without current path.Therefore the hair of light emitting diode L2
Light is still by output level/current control of pin LED2.At this time also due to central processing unit is working properly, driver 104b also root
According to output level/electric current of the equal signals control pin LED0~LED2 received by pin SDA and SCL, and control in turn
Light emitting diode L0~L2's is bright dark.
The circuit diagram of Fig. 2 further includes diode D1~D2.Wherein the function of D1 and D2 be avoid charge node 108 with
The situation of electric current reverse irrigation is generated between rechargeable battery 106 because of voltage difference.Furthermore the circuit diagram of Fig. 2 also includes a transient state
Voltage suppression diode D3 can induce current into ground connection when voltage is excessive and damage to avoid too high voltages to circuit 200.
This external capacitive body C1 can filter out unnecessary noise.
Fig. 3 is the control method flow chart according to an electronic device of the embodiment of the present invention.Method 300 is suitable for above-mentioned electricity
Sub-device 100, and originate in step S302.In step 302, judge whether the voltage of rechargeable battery 106 is enough to control driving
106 normal operation of device processed, if YES then entering step S304；If it is otherwise, entering step 306.In one embodiment, the drive
A disable signal can be sent out when dynamic 106 normal operation of control device, therefore whether can receive the taboo by auxiliary device 114
Stop signal judges whether the voltage of the rechargeable battery 106 is enough to make 106 normal operation of drive dynamic control device.
In step s 304, which is persistently sent out by drive dynamic control device 106, and controls the first luminous dress
Set the bright dark of 102a and the second light emitting device 102b.After the completion of step S304, returns to step S302 and persistently monitor chargeable electricity
The state in pond 106.
In step S306, first light emitting device 102a is provided power to by a charge power supply, and pass through the driving
An access device 114, which provides a current path, in control device 104 makes the first luminous 102a device shine.
Specification and attached drawing of the invention should be citing teaching rather than restriction effect.Any those of ordinary skill is not departing from this
In the case where the spirit and scope of invention and appended claims, it should can do a little change and retouching.
