The beneficial effects of the utility model are:
The utility model reminds user to carry out correct polarity access, and when charging device being carried out to wrong polarity charging, light-emitting diode is lighted the reversal connection of prompting user battery, simple in structure, with low cost.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, as shown in Figure 1, the utility model comprises positive source input A1, positive source output B1, power cathode input A2, power cathode output B2, the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, the first metal-oxide-semiconductor M1, the second metal-oxide-semiconductor M2 and the first diode D1, positive source input A1 respectively with the negative pole of the first diode D1, the first end of the second resistance R 2, the source electrode of the first metal-oxide-semiconductor M1 is connected with positive source output B1, the positive pole of the first diode D1 is connected with the first end of the first resistance R 1, power cathode input A2 respectively with the second end of the first resistance R 1, the second end of the second resistance R 2, the grid of the first metal-oxide-semiconductor M1 is connected with the drain electrode of the second metal-oxide-semiconductor M2, the drain electrode of the first metal-oxide-semiconductor M1 is connected with the grid of the second metal-oxide-semiconductor M2 with the first end of the 3rd resistance R 3 respectively, the source electrode of the second metal-oxide-semiconductor M2 is connected with power cathode output B2 with the second end of the 3rd resistance R 3 respectively.
Operation principle of the present utility model is as follows:
When battery polar accesses correct, the grid negative pressure drop of the first metal-oxide-semiconductor M1, the first metal-oxide-semiconductor M1 conducting, conducting after the grid positive pressure drop of the second metal-oxide-semiconductor M2, output voltage equals cell voltage, work as when battery pole back connection, after the grid positive pressure drop of the first metal-oxide-semiconductor M1, end, the grid no-voltage of the second metal-oxide-semiconductor M2 also ends, the first diode D1 lights the reversal connection of prompting user battery, this circuit can be used for replacing common diode, because the conducting resistance of the first metal-oxide-semiconductor M1 and the second metal-oxide-semiconductor M2 is far smaller than silicon diode, so substantially can off-energy.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection range of the present utility model.
