SY3511

Linear charging, synchronous boost discharge, built-in charging and discharging power MOS. The chip internally sets a 1A charging current. The KEY switch controls the boost discharge module, and the discharge automatically ends after the load is full. Synchronous boost maximum output current 1A. Unique boost output thermal regulation technology. Trickle/constant current/constant voltage charging, and has a thermal regulation function that maximizes the charging rate without the risk of overheating. C/10 charging termination, automatic recharging. Preset 4.2V charging voltage, accuracy up to ±1%. Discharge output overcurrent, short circuit, overvoltage, and overtemperature protection. 4 LED battery level indicators, charging and discharging indicators, and fault indicators. Double-click to turn the flashlight on/off. Product reference application diagram
