CXEP33120 is a single-chip lithium ion battery with lithium protection constant current/constant voltage linear power management chip. It integrates lithium protection of single-chip lithium battery and charge management of lithium battery. The charging voltage is limited to 4.2V, 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, CXEP33120 will automatically end the charging process. When the input terminal (plug or USB power supply) is unplugged, CXEP33120 automatically enters the low current state, and the battery leakage current will drop below 2μA. CXEP33120 can also be set to stop working state to reduce the power supply current to 25μa.
Other features include: charging current monitoring, input low voltage blocking, automatic recharging, charging full and start charging signs.
