CXLB7306是一款专门为大容量锂电池系统设计的高达3A充电电流的开关型单节锂电池充电芯片，同时此芯片也可以逆向操作，从电池端升压给输出至少5V/3A的电流（OTG）。CXLB7306采用了充电领域最先进的内阻补偿技术，并可由客户外设内阻补偿程度。同时它还提供系统用电的路径，可外设充电电流，充电截止电流，输出限流，NTC等众多功能。CXLB7306是目前业界尺寸最小，以QFN3x3封装实现3A充电，3AOTG的锂电池充电芯片。</span>
CXLB7306 is a switching Li-Ion battery charger capable of delivering up to 3A of charging current to the battery and also capable of delivering up to 2.5A in boost OTG operation, with extremely high efficiency in both charging mode and OTG mode. For charging, it uses a proprietary control scheme that eliminates the current sense resistor for conventional constant current control, maximizing efficiency, reducing charging time and reducing costs. It can also output a 5V voltage in the reversed direction by boosting from the battery. It only needs a single inductor to provide power bi-directionally. CXLB7306 is truly an ideal all-in-one solution for battery charging and discharge applications, such as power banks, smart phones, and tablets with only one USB port that can be used for both charging battery and USB OTG function. CXLB7306 is suitable for charging a 4.2V Li-ion battery. EJCXLB7306s in QFN3x3-20 FC package.
