The cxlb7261b is a switch charging circuit with dynamic path management for a single 4.35v lithium battery. The cxlb7261b can provide 2.5A charging current, which is especially suitable for mobile power supply, tablet computer and other devices equipped with large capacity lithium battery. CXLB7261B The internal integrated high current synchronous step-down module, charging control module, dynamic path management, input current limit automatic detection, and all kinds of functions and protection circuits required for lithium battery charging, such as trickle current, constant current, constant voltage charging; battery over temperature protection; charging indication; charging current setting does not need expensive milliohm resistance; charging time is too long to close; IC Short circuit protection and over temperature protection, etc. The sys and batt dual port reverse cut-off function of cxlb7261b also prevents the battery from reverse filling when the input interface is short circuited. Cxlb7261b also provides battery removal detection
