  JZ55182 Charge cutoff voltage can be adjusted via an external resistor, charge currentAlso, the setting can be adjusted via an external resistor. When the charging current drops to the set value,1/10 At that time,JZ55182 The charging process will automatically terminate, continuously monitoring the electricity.Pond voltage, automatically recharges when it drops to a certain threshold. When input voltage（USB Source orAC Adapter removed, battery terminal leakage occurs25uA。

  JZ55182 Integrated charging and full charge prompts, as well as error indicators.Robust protection features include overvoltage protection(OVP)BatteryOVP、Battery Short Circuit Protection, Thermal Shutdown, Battery Temperature Monitor, Configurable TimerTimer to prevent long-term charging of discharged batteries.
