CXLB73202 is a perfect monolithic lithium titanate lithium ion battery constant current/constant voltage linear power management chip. Its thin size and small outer packaging make it convenient for portable application. What is more worth mentioning is that CXLB73202 is specially designed for USB supply
Electrical specifications. Thanks to the internal MOSFETs, there is no need for external resistance and blocking diode in applications. During high energy operation and high peripheral temperature, thermal feedback can control the charging current to reduce the chip temperature. The charging voltage is limited to 2.8V, and the charging current is adjusted by an external resistor. After reaching the target charging voltage, when the charging current drops to 1/10 of the set value, CXLB73202 will automatically end the charging process. When the input terminal (plug or USB power supply) is unplugged, CXLB73202 automatically enters the low current state, and the battery leakage current will drop below 2μA. CXLB73202 can also be set to stop working state to reduce the power supply current to 18μa. CXLB73202 built-in battery reverse connection protection circuit ensures that the chip automatically enters the protection state when the battery is connected reverse to ensure that the IC is not broken down and causes accidents caused by battery self-discharge. Other features include: charging current monitoring, input low voltage blocking, automatic recharging, charging full and start charging signs.
