SY7658
Sexual charging, synchronous boost discharge, built-in charging and discharging power MOS. The chip has a default setting of 0.5A charging current, with optional versions of 0.2A, trickle/constant current/constant voltage charging, and a thermal regulation function that maximizes charging rate without the risk of overheating. C/10 charging termination, automatic recharging. Adaptive adapter voltage, VINDPM: 4.6V. Preset 4.2V charging voltage, accuracy up to ±1%. Supports simultaneous charging and discharging. Synchronous boost maximum output current 0.5A. Constant discharge output, no-load power consumption: 60uA. Discharge output overcurrent, short circuit, overvoltage, and overtemperature protection. 2~4 LED battery level display, charging and discharging indication. Single click KEY to switch boost output.
