I. Overview:

  JZ3765 IsPWM Multi-type battery charging management with voltage reduction modeIntegrated circuit, independently manages charging for multiple batteries, features sealedCompact in size, with minimal peripheral components, and simple to use.

  JZ3765 Features涓流，恒流和恒压充电模式，very suitableIntegrated charging management for lithium-ion, lithium iron phosphate, and lithium titanate batteries.In constant voltage charging mode,JZ3765 Adjust the battery voltage externallyFeedback resistance-set voltage; Charging in constant current modeCurrent flows through an external resistor setup.

For deeply discharged lithium-ion batteries, when the battery voltage falls below the constant voltage charge...Voltage66.5%(Typical Value)At the time,JZ3765Please use the constant setFlowing current17.5%Trickle charge the battery. At constantDuring the pressure charging phase, the charging current gradually decreases, as the charging current drops...As low as the constant current charging current16%When charging is complete. At chargingCompletion status, if the charging current rises again to the constant current charging currentThe58.8%Above, the automatic start of a new charging cycle. When inputPower failure or when the input voltage is lower than the battery voltage.JZ3765Automatically enters sleep mode.

Other features include low-voltage lockout input and over-voltage protection at the battery terminal.With charging status indicators, etc.
