IP2368 is a lithium battery charge management chip that integrates AFC/FCP/PD2.0/PD3.0 input fast charge protocol and synchronous boost converter.
    IP2368's high integration and rich functions, only one inductor to achieve synchronous voltage reduction and boost function, only a few peripheral devices in the application, effectively reduce the size of the overall solution, reduce the BOM cost.
    IP2368 supports 2/3/4/5/6 series cells, and the number of series cells can be selected through external resistance; Resistance IP2368 support choice in common or lithium iron phosphate batteries, lithium battery resistance can be set up with voltage, lithium batteries voltage can be set up as follows: 4.15 V / 4.2 V / 4.35 V / 4.4 V, 4.3 V/lithium iron phosphate batteries voltage can be set to: 3.5 V / 3.55 V / 3.6 V / 3.65 V / 3.7 V.
    The IP2368's synchronous switching charging system provides up to 5.0A charging current, which can be set to the maximum charging power or battery side charging current through an external resistor, up to 100W. IP2368 built-in IC temperature, battery NTC temperature and input voltage control detection loop, can intelligently adjust the charging current according to different power chargers.
    The IP2368 has a built-in 14-bit ADC that accurately measures charge input voltage and current, and battery voltage and current. IP2368 built-in power calculation method, can obtain the battery power, charging voltage, charging current and other information through the IIC.
    The IP2368 supports two charging status indicators.
