The cxlb7264a is a switch type single or two lithium ion / lithium polymer battery charge management chip, which is very suitable for the charge management application of portable devices. The cxlb7264a integrates high-precision voltage and current regulators, precharge, charging state indication and charging cut-off functions, and is packaged in msop-10. The battery charging of cxlb7264a is divided into three stages: pre charge, CC / constant current and CV / constant voltage. The constant current charging current is determined by the external resistance, and the constant voltage charging voltage can be adjusted by the external resistance. Cxlb7264a integrates over-voltage and short-circuit protection to ensure the safe operation of charging chip. Cxlb7264a integrated intelligent battery detection function and timeout error recovery function, convenient for users
