Portable mobile electronic devices there are a lot of application of two or three series of lithium batteries, the traditional step-down type charging management requires the input voltage is higher than the battery voltage, the collocation of the adapter voltage standard is not unified, the consumers of this kind of lithium battery and inconvenience, in addition, a dedicated charging adapter also caused the waste, if charging adapter consumers lost or difficult to find, also can cause the terminal cannot receive timely product use or need to purchase other special charging adapter, due to the popularity of mobile phones, 5 V power supply charger has been the use of great size, plus USB 5 V was international general standard interface, and all kinds of common computer terminal has rich 5 V output interface, for 8.4 V and 12.6 V lithium battery power supply of the application of products, the best way is to use general mobile phone adapter charging, booster type charging management arises at the historic moment, booster type charging management from the step-down type is that the input voltage is lower than the battery voltage, USB_5V so that it can be used as the two series of three series of lithium battery charger, portable mobile electronic equipment factory with a USB charging line is the perfect solution to the above application, save the end products the machine cost, avoid the waste of materials,

Shenzhen yong fukang technology co., LTD. Offer two string for 8.4 V and 12.6 V three series of lithium battery, launched a series of USB 5 V input booster charge management scheme, the perfect solved this kind of product of charging,

USB_5V input for two series 8.4 V rechargeable lithium battery management chip: CS5080, CS5082, CS5086, CS5090; For three series 12.6 V rechargeable lithium battery management chip: CS5095, each model all have input adaptive function, USB interface can be of any size current normal charging, maximum charging current of 1.5 A, on the other hand, have complete A trickle, constant current, constant voltage charging process, various safety protection measures and charging status indication, most models with the function of the NTC temperature control, CS5086 also have power balance function, stability of the circulation of the battery charging times and greatly ascend, booster type charging management chip is suitable for application in bluetooth stereo, juicer, POS machines, handheld printer, drones, fascia guns, electric tools and other products field in the future have broad market prospects,

Application features are as follows:
