Dual-cell series lithium battery boost charging IC with charge balancing function--IP2326
IP2326 is a boost charging management IC that supports dual-cell series lithium batteries/lithium-ion batteries. IP2326 integrates power MOS and adopts a synchronous switching architecture, which requires fewer peripheral devices during application, reduces the size of the overall solution, and reduces the BOM cost. IP2326's boost switching charging converter operates at a frequency of 500KHz; 15W input charging, 5V input, 8V/1A output conversion efficiency 94%, 8V/1.5A output conversion efficiency 92%. IP2326 has an input voltage limiting function that can intelligently adjust the charging current to prevent the adapter from being pulled. IP2326 supports external resistors to adjust charging current, charging current. IP2326 supports external resistors to adjust charging current, charging voltage, input undervoltage threshold, input overvoltage threshold, charging timeout threshold and other parameters; IP2326 integrates a charging balancing circuit, which can be used during charging. It detects the voltage of each battery at all times to ensure the balance of the voltages of the two batteries; IP2326 integrates NTC protection function and cooperates with NTC resistor.
IP2326 is packaged in 4*4mm QFN24.
