Car charger introduction

Car charger is designed to facilitate the use of vehicle power supply at any time for digital products. For the conventional car battery (12V car, 24V car charger power supply truck), widely used in various portable handheld devices, lithium battery charging, such as mobile phone, PDA, GPS etc.; car charge should not only consider the actual demand of rechargeable lithium batteries (constant voltage constant current CV, CC, OVP, and overvoltage protection) taking into account the on-board battery environment (transient voltage spikes, system switching noise interference, EMI etc.); therefore the power management IC car charger selection scheme must satisfy: resistance to high pressure, high efficiency, high reliability, low frequency (Design for EMI) switching power supply chip; popular talk is "rugged".

Car charger is designed to facilitate the use of vehicle power supply at any time for digital products. At present, some high-end car charger generally includes 2 USB interface, can simultaneously charge for two digital products, of course, there is only one USB interface. These products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, four heavy security protection function, to ensure safe use. Car charger in the vehicle at the same time, also can realize the household, car charger, charging, USB charging three in one function.
Features: multifunction, portability, fashion, security
With the development of the automobile industry, the on-board charger has been widely used, showing the characteristics of multifunction, portability and fashion. Currently on the market, there are more influential car charger Ma Liqiang and other products. This product unique power management program, the output current up to 3A, is currently the world's fastest charging USB charger.
Multi function: can meet the different conditions of charging; dual USB output interface, can be charged for a number of electronic products.
Portability: portability is a major trend in the development of electronic products, the product volume is concentrated, easy to carry.
Fashion: for the owners of this high-end consumer groups, the car charger is also the focus of attention for manufacturers.
