Abstract
The utility model relates to an integrated circuit vehicle voltage regulator who uses on car. The temperature-sensing VMOS intelligent device mainly comprises a resistor, a voltage-stabilizing tube, an integrated block, a diode and a temperature-sensing VMOS intelligent device. The on-off of the temperature sensing VMOS intelligent device is controlled by utilizing the high and low output levels of the integrated block, so that a high-precision voltage stabilization adjusting function is implemented. The voltage regulator has the advantages of small volume, convenient installation, no contact, long service life, short circuit protection function, and prevention of damage to elements due to power supply polarity misconnection, and is a vehicle voltage regulator with high regulation precision.
Description
The present invention relates to the integrated circuit voltage regulator for vehicle that uses on a kind of automobile.
As everyone knows, on the traveling automobile electromagnetic potential adjuster or solid-state regulator are housed all at present.Though they all play a positive role for the voltage on the car is stable, must see that still there are many defectives in they.As the electromagnetic potential adjuster, its contact burns out easily, so the life-span is short; Spring tension easily changes, so adjusting is inaccurate, and the output voltage shakiness; Its volume is bigger in addition, and influence is installed.And for example solid-state regulator even normal running is used, also burns out easily, if the driver scrapes fire (bonding) inspection, that has just let alone, so its life-span is shorter.
Purpose of the present invention is exactly in order to overcome above-mentioned drawback, for Hyundai Motor provides a kind of volume little, and the degree of regulation height, contactless, no electromagnetic interference, vibration resistance, the scratch resistance fire, the life-span is long, has overheated and integrated circuit voltage regulator for vehicle short-circuit protection function.
Purpose of the present invention mainly is by being used in combination of ic chip and temperature-sensitive VMOS intelligent device V, thereby the switching of the high and low V of control by the IC output level realizes.
Describe technical characterictic of the present invention in detail below in conjunction with accompanying drawing.Fig. 1 is an integrated circuit voltage regulator for vehicle circuit diagram of the present invention.Among the figure:
R
1～R
4---resistance D
W1～D
W2---voltage-stabiliser tube
IC---integrated package D
1～D
2---diode
V---temperature-sensitive VMOS intelligent device+---positive terminal
----negative terminal F---binding post
Be described in further detail circuit connecting mode of the present invention now.Resistance R
1, R
3An end and 7 pin of ic chip be connected to positive terminal+on; R
1The other end respectively with R
2An end and 2 pin of IC join; R
3The other end respectively with voltage-stabiliser tube D
W1Negative pole and 3 pin of IC join; R
2The other end, D
W1Positive pole, 4 pin and the D of IC
W2Positive pole and the S pin of temperature-sensitive VMOS intelligent device V with being connected to diode D
1Positive pole; 6 pin and the R of IC
4An end join; R
4The other end respectively with D
W2Negative pole and the G pin of V join; The D pin of temperature-sensitive VMOS intelligent device respectively with D
2Negative pole and binding post F join; D
1Negative pole and D
2Positive pole with being connected on the negative terminal one; Negative terminal-bonding ground connection.
Describe function of the present invention and operation principle below in detail.After automotive ignition started, 3 pin of IC were at R
3And D
W1Effect under stable voltage U is arranged
3When the total voltage of car load is lower than set point (as 7V, 14V, 28V etc.), the 2 pin voltage U of IC
2Be lower than U
3, i.e. U
2＜U
3The time, IC output high level and through R
4Trigger the V conducting, thereby exciter current of generator is provided, so generator for electricity generation work, its output voltage appropriateness raises; When general supply voltage is higher than set point, the 2 pin voltage U of IC
2Be higher than U
3, i.e. U
2＞U
3The time, the IC output low level, so V can not be triggered and be in dissengaged positions, generator does not generate electricity.Periodic duty so again and again, thus make output voltage be in stable state always.
In addition, because D
W2Positive pole respectively with S pin and the D of V
1Positive pole join; D
W2Negative pole and G pin and the R of V
4Contact join, so it has short-circuit protection function.
Again because D
1Positive pole respectively with D
W2S pin anodal and V joins; D
1Negative pole respectively with D
2Positive pole and negative terminal-join (bonding ground connection simultaneously), damage electronic component when preventing the electric power polarity misconnection.
The present invention is an automobile voltage stabilizing product independently, and it makes with known technology similar, if according to circuit with each electronic component firm welding, and be installed in the housing that plastics or bakelite make and get final product.
During use, positive terminal+end anodal with storage battery respectively and dynamo field coil joins; The other end of binding post F and magnet exciting coil joins; The negative pole of negative terminal one and storage battery joins and gets final product.
In sum, the present invention not only volume is little, and is easy for installation; and contactless, the life-span is long, has short-circuit protection function and damages the element function with preventing the electric power polarity misconnection; a kind of really degree of regulation height, vibration resistance, the integrated circuit voltage regulator for vehicle of scratch resistance fire.
