Cxlb7266a is a switch type 1 to 4 lithium ion / lithium polymer, single or two lead-acid battery charge management chips, which is very suitable for the charge management application of portable devices. The cxlb7266a 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 cxlb7266a is divided into three stages: precharge, 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. Cxlb7266a integrated battery temperature detection, over-voltage and short-circuit protection to ensure the safe operation of the chip. Cxlb7266a integrates intelligent battery detection function and timeout error recovery function, which is convenient for users
