3. Overview

  CJ4056D A complete single-section lithium-ionBattery utilizes a constant current/Constant Voltage Linear ChargerBattery positive and negative pole reverse connection protection; bottom with heat sinkThe ESOP8 Packaging and fewer external components.CJ4056D The ideal choice for portable applications.CJ4056D SuitableUSB Power Supply and AdaptersSource work. Utilized internallyPMOSFET Structure, plusAnti-reverse charge circuit, no external isolation diode required. HeatFeedback can adaptively adjust the charging current forUnder high-power operation or elevated environmental temperatures, for the chipTemperature is limited. Filled with cut-off voltage.4.2 V...andThe charging current can be externally set through a resistor.As the charging current drops after reaching the float voltageSetpoint1/10 At the moment,CJ4056D Automatically terminate the inflationElectrical cycle.

When the input voltage power fails.CJ4056D Automatic FeedingEnter a low current state, reducing the battery leakage current to0.2uA Below.CJ4056D Other features include electricalOriginating from Adaptability, Battery Temperature Monitoring, Under-Voltage Lockout, Self-Motion charging and two indicators for charging and completion.LED Status pin.
