I. Overview:

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

  JZ3765 Features涓流，恒流，and恒压 charging modes, highly suitableIntegrated charging management for lithium-ion, lithium iron phosphate, and lithium titanate batteries.In constant voltage charging mode,JZ3765 Adjust the battery voltage externallyVoltage set by the feedback resistance; Charging in constant current modeCurrent flows through an external resistor setup.

For deeply discharged lithium-ion batteries, when the battery voltage drops below the constant voltage charging threshold,Voltage66.5%(Typical Value)At that time,JZ3765Use the set constantFlowing current17.5%Trickle charge the battery. At a constant...During the pressure charging phase, the charging current gradually decreases, when the charging current dropsAs low as the constant current charging current16%When, charging is complete. At chargingCompletion state, 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 enter sleep mode.

Other features include low voltage lockout and battery terminal overvoltage protection.And charging status indicators.
