Overview:

    JZ3705SurePWMBattery with voltage reduction mode or lithium iron phosphateBattery Charging Management Integrated Circuit, Independent for Single or Multiple CellsBattery charging, including lithium-ion or iron-phosphate lithium batteries, is automatically managed.Small封装, fewer peripheral components, and simple to useAnd so on.

    JZ3705 Features constant current and constant voltage charging modes, ideal forCharging of lithium batteries or lithium iron phosphate batteries. Constant voltage chargingPattern, constant voltage charging voltage set by external resistance voltage divider networkSet; In constant current charging mode, the charging current passes through an externalSectional resistance settings.

For deeply discharged batteries, when the battery voltage falls below the setConstant voltage charging voltage setting66.7%At that time,JZ3705Please provide the Chinese content to be translated.Set constant current charging current15%Apply trickle charge to the batteryFlow charging. During the constant voltage charging stage, the charging current gradually decreases.Small, when the charging current is reduced to the value set by the external resistorWhen charging is complete. In the state of charging completion, if the batteryVoltage drops to the set constant voltage charging level.91.1%When power is disconnected, the automatic start of a new charging cycle is initiated.If electricity or input voltage is lower than battery voltage.JZ3705SinceEnter low-power sleep mode.

Additional features include low-voltage lockout, battery temperature monitoringBattery over-voltage protection and charging status indication, etc.
