IP2369 Description:
    IP2369 is a lithium battery charging and discharging management chip that integrates input/output fast charging protocols such as AFC/FCP/PD2.0/PD3.0/PD3.1 and synchronous buck boost converters, with a charging and discharging power of up to 45W;
    IP2369 supports 2/3/4/5/6 series connected battery cells, and the number of series connected battery cells can be selected through external resistor settings; IP2369 supports external resistors and can set battery types, with a full charge voltage of 3.65V/4.1V/4.2V/4.35V/4.4V.
    IP2369 has a built-in IC temperature, battery NTC temperature, and input voltage control detection loop, which can intelligently adjust the charging current based on the recognized charger power.
    IP2369 standby power consumption can be as low as no more than 100uA.
    IP2369 has a built-in 14 bit ADC, which can accurately measure input voltage and current, battery voltage and current, etc. IP2369 charging and discharging voltage, charging current and other information can be obtained through I2C.
    IP2369 supports 4 battery indicator lights, which can display battery level and charging/discharging status.
