CXLB73230 switch type dual cell lithium battery charging control chip, high-precision reference voltage pre charging, constant current and constant voltage charging

The CXLB73230 series is a switch type dual cell lithium battery charging control chip. This chip includes charging status detection, charging process, temperature detection, etc. It also integrates a high-precision reference voltage module internally. This chip adopts SOP-8 package CXLB73230 charging, which includes three modes: pre charging, constant current charging, and constant voltage charging. During constant current charging, the current is 5 times the pre charging current; Pre charge state when voltage is below 6.5; When the voltage is higher than 6.5V, it enters constant current charging mode, and the charging current at this time is 5 times that of pre charging. The charging current is set by an external resistor.
