Description
Technical field
This utility model relates to battery status indicating circuit, specifically a kind of novel Battery Status Indicator.
Background technology
Battery Status Indicator is a kind of circuit common in Electronic Design.Existing Battery Status Indicator is limit due to self structure, it is necessary to just can be operated under higher supply voltage, thus causes that its power consumption is big, causes that its indicating effect is not good on the other hand on the one hand.Based on this, it is necessary to invent a kind of brand-new Battery Status Indicator, to solve the problem that existing Battery Status Indicator power consumption is big, indicating effect is not good.
Summary of the invention
This utility model is in order to solve the problem that existing Battery Status Indicator power consumption is big, indicating effect is not good, it is provided that a kind of novel Battery Status Indicator.
This utility model adopts the following technical scheme that realization: a kind of novel Battery Status Indicator, including NPN transistor, PNP transistor, light emitting diode, the first resistance, the second resistance, the 3rd resistance, the 4th resistance, the 5th resistance, electric capacity；
Wherein, the base stage of NPN transistor is connected with positive power source terminal by the first resistance, and the base stage of NPN transistor is connected with negative power end by the 4th resistance；The colelctor electrode of NPN transistor is connected with positive power source terminal by the second resistance, and the colelctor electrode of NPN transistor is connected with the base stage of PNP transistor；The emitter stage of NPN transistor is connected with negative power end by the 5th resistance；The colelctor electrode of PNP transistor is connected with negative power end；The emitter stage of PNP transistor is connected with positive power source terminal by the 3rd resistance；The anode of light emitting diode is connected with the emitter stage of NPN transistor, and the negative electrode of light emitting diode is connected with positive power source terminal；The two ends of electric capacity are connected with the emitter stage of PNP transistor and the anode of light emitting diode respectively.
During work, positive power source terminal is connected with the positive pole of battery, negative power end is connected with the negative pole of battery.Specific works process is as follows: in the moment switched on power, due to electric capacity two ends voltage can not transition, electric capacity is equivalent to short circuit, and the emitter voltage of NPN transistor is more than zero, the base voltage of NPN transistor is less than the conduction voltage drop of NPN transistor, and NPN transistor ends.Along with the voltage at electric capacity two ends gradually rises, NPN transistor emitter voltage is gradually lowered, and the base voltage of NPN transistor gradually rises to the conduction voltage drop more than NPN transistor, and NPN transistor turns on, and PNP transistor turns on.Now, the voltage at electric capacity two ends discharges through PNP transistor, equal to the voltage between positive power source terminal and negative power end, the voltage at light emitting diode two ends adds that the voltage at electric capacity two ends deducts the saturated tube voltage drop of PNP transistor again, and the voltage at light emitting diode two ends is more than the conducting voltage of light emitting diode, light emitting diode is lighted.After treating the voltage release at electric capacity two ends, light emitting diode extinguishes.Then, the voltage at electric capacity two ends gradually rises again, and light emitting diode is lighted again.Circulating with this, when the voltage between positive power source terminal and negative power end remains certain value, light emitting diode will constantly glimmer.Therefore, namely be can indicate that the newness degree of battery by the flicker frequency of light emitting diode: if new battery, then owing to the voltage between positive power source terminal and negative power end is higher, the flicker frequency of light emitting diode is very fast；And if used batteries, then owing to the voltage between positive power source terminal and negative power end is relatively low, the flicker frequency of light emitting diode is slower.Based on said process, compared with existing Battery Status Indicator, a kind of novel Battery Status Indicator described in the utility model achieves battery status instruction based on brand-new circuit theory, it is namely operable at lower supply voltages, thus significantly reduce power consumption on the one hand, significantly improve indicating effect on the other hand.
This utility model is rational in infrastructure, it is ingenious to design, and efficiently solves the problem that existing Battery Status Indicator power consumption is big, indicating effect is not good, it is adaptable to battery status indicates.
