Description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the circuit diagram of the first embodiment of this utility model ignition.
Specific embodiment
Fig. 1 is referred to, is the module diagram of the first embodiment of this utility model ignition.As shown in figure 1,
In the ignition that this utility model first embodiment is provided, at least include lithium cell charging managing chip U1, the lithium electricity
1st pin of pond charging management chip U1 is sequentially connected in series second resistance R2, photodiode D1, and photodiode D1 is just
It is 5V to terminal voltage, the 2nd pin of the lithium cell charging managing chip U1 is grounded, the lithium cell charging managing chip U1 the
Three pins connect lithium battery, are also connected in series a switch K, heating wire R3, the other end ground connection of resistance；The lithium cell charging pipe
The 5th pin serial connection connection first resistors R1 of reason chip U1, the other end ground connection of first resistor R1, the lithium cell charging management
The output voltage of the 4th pins of chip U1 is 5V.Input of 4th foot of power supply IC for 5V, while providing charging for D1 indicates electricity
Pressure, when charging normal, 1 foot is low level, and display lamp is bright.3rd foot is charging outfan, connects the positive pole of lithium battery, and built-in voltage takes
Sample circuit, after cell voltage is full of saturation, 1 foot is changed into high electricity by the built-in sampling voltage feedback circuit of 3 feet by built-in MCU
Flat, display lamp goes out.5 feet are that charging current adjusts resistance, just can change charging within the specific limits by the resistance for changing R1
Electric current (sets maximum current value as 600MA).
When being embodied as, the lithium cell charging managing chip U1 can select model 4054 or LPS4060 or other
The chip of this function can be realized.The resistance of first resistor R1 is 2000 ohm.The resistance of second resistance R2 is 2000 ohm.
Electric circuit characteristic is as follows：
First, Charge Management, has good charge protection effect using special lithium cell charging managing chip, matches somebody with somebody to battery
There are the programs such as charged state instruction.
2nd, load management, the heating wire R3 impedances of this lighter be according to the voltage of lithium battery and Capacity design out
A kind of resistive exothermic material, volt-ampere linear characteristic are good, can effectively limit the overdischarge of battery, and adaptive ability is strong, reduces
Circuit design components and parts.
3rd, the circuit of whole circuit is simple, material and low production cost, and cost performance is high, because of the few fault rate of components and parts also very
Low, without quiescent current when not using, it is suitable for long-time and places.
Design of this utility model by above example, can accomplish the various advantages according to poly-lithium battery, letter
The charging control circuit of complexity is changed, there is provided the cost performance of product, has reduced product cost, reduce the fault rate of product.
This utility model is described according to specific embodiment, but it will be understood by those skilled in the art that without departing from
During this utility model scope, various change and equivalent can be carried out.Additionally, the specific field for adaptation this utility model technology
Close, many modifications can be carried out to this utility model without deviating from its protection domain.Therefore, this utility model is not limited to here public affairs
The specific embodiment that opens, and including all embodiments for dropping into claims.
