What is a car charger?

Car chargers, car chargers that are routinely powered by car batteries (car 12V, truck 24V), are used extensively in the charging of lithium batteries for various portable and handheld devices, such as: mobile phones, PDAs, GPS, etc.; To consider the actual needs of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP), but also take into account the harsh environment of the car battery (transient spike voltage, system switching noise interference, EMI, etc.); The selected power management IC must meet both the switching power supply chip that is resistant to high voltage, high efficiency, high reliability, and low frequency (which is good for EMI design).

The Car Charger uses the cigarette lighter on the car to connect to the mobile phone to charge the mobile phone through the charger transformer, which is convenient for the car family to use outside, and can also use the mobile phone normally when charging.

The car charger uses a car cigarette lighter as a power outlet to directly charge the phone. Since the voltage provided by the car is low, only the overload protection circuit is needed inside the car charger. The front end of the car charger socket is designed with a fuse. When the current exceeds the overload protection circuit, the fuse is immediately blown and protected. Of course, compared with the purchase of a travel charger, when purchasing a car charger, there is an additional interface judgment, and the plug connected to the car should be firmly inserted in the car cigarette lighter. Nowadays, there are a variety of functions in one car charging, which not only has the basic car charger function, but also can transmit the music of audio playback devices (such as mobile phones, MP3s, etc.) to the car radio through FM charging. Play it out by car stereo.
