CXLB73206 is a perfect monolithic lithium ion battery constant current/constant voltage linear power management chip. Its thin size and small outer packaging make it convenient for portable application. No external resistor or blocking diode is required for application. High energy operation and high
At the peripheral temperature, thermal feedback can control the charging current to reduce the chip temperature. The charging voltage is limited to 4.2V and the charging current is fixed to 500mA. After reaching the target charging voltage, when the charging current drops to 1/10 of the set value, CXLB73206 will automatically end the charging process. When the input terminal (plug or USB power supply) is unplugged, CXLB73206 automatically enters the low current state, and the battery leakage current will drop below 2μA. CXLB73206 can also be set to stop working state to reduce the power supply current to 25μa. CXLB73206 built-in battery reverse connection protection circuit ensures that the chip automatically enters the protection state when the battery is reverse connected. CXLB73206 supports input anti-reverse connection protection. When the input is reversed, the chip enters the automatic protection state.
Other features include: charging current monitoring, input low voltage blocking, automatic recharging, charging full and start charging signs.
