IP2326 is a 2-section / 3-section series lithium battery booster charging IC that supports 15W fast charge.
    IP2326 integrates power MOS and adopts synchronous switching architecture, so that it requires few peripheral devices in application, and effectively reduces the overall solution size and BOM cost.
    IP2326 booster switch charging converter operating frequency 500KHz; Maximum 15W input charging, 5V input, 8V/1A output conversion efficiency of 94%, 8V/1.5A output conversion efficiency of 92%.
    The IP2326 has input voltage limiting function, which can intelligently adjust the charging current and adapt the load capacity of the adapter.
    The IP2326 supports external pins to select whether to set up 2 or 3 strings of lithium battery charging; The IP2326 supports external resistors to adjust charging current, charging voltage, input undervoltage threshold, input overvoltage threshold, and charge timeout threshold.
    IP2326 can apply for fast charge input according to the current battery voltage to improve charging efficiency and shorten charging time.
    The IP2326 integrates a 2-series charge equalization circuit, which can detect the voltage of each battery during charging to ensure the voltage balance of the two batteries.
    IP2326 integrated NTC protection function, with NTC resistance to achieve charging NTC protection.
    The IP2326 comes in a 4*4mmQFN24 package.
