Cxlb7307 is a single lithium battery switch charging with charging current of 2.5A. It integrates the function of dynamic path management. The internal resistance of the internal path switch is only 50mohm, which allows the system to maintain the normal operation of the system when there is no battery. The charging current setting of the cxlb7307 does not require expensive precision resistors. It also has the function of input current automatic detection and maintenance of input voltage to ensure that the input interface will not be pulled dead when the input power supply is insufficient. Other functions necessary for lithium battery charging, cxlb7307 is also available, such as abnormal battery temperature shutdown, charging timeout shutdown, overcurrent, overheating protection, etc
