Description
Technical field
This utility model relates to automobile auxiliary technical field of electricity, particularly relates to a kind of onboard charger with rapid charge protection circuit.
Background technology
Automobile is more and more universal in the life of people, and a lot of people go out provisional capital and be unable to do without automobile, and it is also unavoidable for using electronic product onboard.Automobile cigarette lighter is the interior main approach providing power supply of car.
Existing onboard charger is typically all power taking on cigar lighter, and after reduction voltage circuit, lowering and stabilizing blood pressure is to after 5V, delivers to USB interface output.Although the voltage after blood pressure lowering is 5V, but, when this onboard charger is to electronic equipment chargings such as mobile phones, heating when all can produce charging.Owing to charging process is carried out the most at night, battery-heating can cause the consequence that such as fire etc. cannot be expected.
Utility model content
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of onboard charger with rapid charge protection circuit, by rapid charge circuit and its protection module, it is achieved be charged electronic product the most onboard.
This utility model adopts the technical scheme that:
A kind of onboard charger with rapid charge protection circuit; including charger body; described body connects cigar lighter input 12V voltage; and it is depressurized to 5V by reduction voltage circuit; described reduction voltage circuit is connected to rapid charge circuit; described rapid charge circuit includes direct current dividing cell, rapid charge chip; described direct current dividing cell is connected to described reduction voltage circuit; and branching to rapid charge chip, described rapid charge chip includes output over-voltage protection module, output short circuit protection module and remote shutdown protection module.
Further, described rapid charge chip is CHY103D.
Further, described rapid charge circuit also includes that output plug, described output plug are USB.
The beneficial effects of the utility model are:
(1) function needed for onboard charger supports QC 3.0, and compatible with Quick Charge 2.0 product；
(2) CHY103D chip has abundant defencive function, it is ensured that during charging, charger is all protected with battery；
(3) charging circuit is simple, and element application is few, easy to maintenance.
(4) for the battery charger of the mobile devices such as panel computer, smart mobile phone, Bluetooth adnexa and USB power take-off mouth.
Accompanying drawing explanation
Accompanying drawing 1 is charge protector figure of the present utility model.
Being numbered in accompanying drawing:
1. direct current dividing cell；2. rapid charge chip；
3. interface board.
Detailed description of the invention
The detailed description of the invention of the onboard charger to this utility model below in conjunction with the accompanying drawings with rapid charge protection circuit elaborates.
The onboard charger with rapid charge protection circuit includes charger body, and described body connects cigar lighter input 12V voltage, and is depressurized to 5V by reduction voltage circuit.By rapid charge circuit to output plug USB.
Seeing accompanying drawing 1, reduction voltage circuit is connected to rapid charge circuit, and 5V voltage is sent to rapid charge circuit.Rapid charge circuit includes direct current dividing cell 1 and rapid charge chip 2; direct current dividing cell is connected to reduction voltage circuit; and branching to rapid charge chip, rapid charge chip includes output over-voltage protection module, output short circuit protection module and remote shutdown protection module.The chip model that rapid charge chip is selected is that CHY103D, CHY103D have abundant defencive function, and its output over-voltage protection module can prevent from exporting the self adaptation output over-voltage protection exceeding set output voltage 120%.Output short circuit protection module detection partial short-circuit also stops power output to prevent cable and the overheated soft short-circuit protection of output of adapter.Remote shutdown protection module can make the remote shutdown of power receiving equipment remote shutdown adapter protect in the case of fault being detected.Final output voltage outwards transmits connection through interface board 3.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
Claims (3)
1. an onboard charger with rapid charge protection circuit; including charger body; described body connects cigar lighter input 12V voltage; and it is depressurized to 5V by reduction voltage circuit; it is characterized in that: described reduction voltage circuit is connected to rapid charge circuit; described rapid charge circuit includes direct current dividing cell, rapid charge chip; described direct current dividing cell is connected to described reduction voltage circuit; and branching to rapid charge chip, described rapid charge chip includes output over-voltage protection module, output short circuit protection module and remote shutdown protection module.
