The cxlb7284a is an integrated switching single and double lithium battery charging management chip The maximum charging current of the cxlb7284a is 2A cxlb7284a adjusts the charging voltage

The cxlb7284a is an integrated switching single and double lithium battery charging management chip, The maximum charging current of the cxlb7284a is 2A. The cxlb7284a adjusts the charging voltage and current of the lithium battery through the constant voltage control ring (CV) and the constant current control ring (CC). At the same time, the cxlb7284a also integrates the temperature protection, the maximum charging time limit, the output short circuit and other protection functions, through NTC Detection of battery temperature can realize the function of battery overheat protection, and two LED indicators indicate the battery charging state
