The car charger is an accessory for charging digital products anytime and anywhere with the convenience of the car power supply, saving you the cost of the battery. Such products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, and four-fold safety protection functions to ensure that people can use them safely. And because of his own simplicity, convenience, and speed, he has become an indispensable daily necessities in people's driving.

The car charger uses the car cigarette lighter as a power socket to directly charge the mobile phone. Since the voltage provided by the car is low, only an overload protection circuit is required inside the car charger. The front end of the car charger socket is designed with a fuse. When the current exceeds the range of the overload protection circuit, the fuse will be blown immediately to protect it. Note: You can only charge when the car engine is started!

There are three main types of car chargers, namely:

1. Low-end car charger realized by single-chip 34063A;

2. Rely on 34063+NPN (NMOS) to realize the expansion of the car charger;

3. Rely on car charger with 2576+358+ voltage regulator tube;

4. Rely on XLSEMI to design a single-chip car charger.

The principle of the car charger is to use the car cigarette lighter as the power socket to directly charge the mobile phone. Since the voltage provided by the car is low, only an overload protection circuit is required inside the car charger. The front end of the car charger is designed with a fuse, when the current exceeds the overload protection circuit can withstand the range, the fuse will blow immediately to play a protective role. In addition to charging mobile facilities, the car charger also has a GPS positioning function.

The car charger is composed of circuit board and shell, metal plug, data cable and other components;

Shell: The shell materials are PC, PC/ABS, flame-retardant ABS, HIPS

Metal plug: The plug of the car charger is made of metal material

Data cable: The data cable of the car charger has different sockets, and there are different plugs for different charging devices.

Features of car charger:

1. The computer automatically protects the chip, which can be used with confidence no matter where it is, providing perfect protection for your device when charging;

2. Car charger plug structure, built-in fuse, over-voltage current is too large, the fuse will automatically blow to protect the safety of the machine;

3. The car charger also has a USB interface, which supports various USB interface power output;


4. IPhone/ipad can be charged through the power output interface.
