Description:

SC2322 is a 5V input, boost mode charge management IC, suitable for two-cell series lithium battery. It can adapt to any 5V power supply for charging, and is protected by input overvoltage and undervoltage. SC2322 adopts synchronous boost structure, built-in MOSFET, simple peripheral components. By adjusting the external resistance, the charging current can be adjusted arbitrarily, the maximum support is 1.6A, and the efficiency exceeds 90%.

SC2322 has multiple protection functions: charging timeout, chip overheat feedback adjustment, over temperature shutdown, input over voltage, input under voltage, output over current, output over voltage, output short circuit, NTC temperature protection, etc. In case of abnormality, the LED can be used to indicate abnormality.
