BQ2002FSNG4 Datasheet/PDFBattery chargers are widely used in many different applications, from consumer electronics to military applications. The BQ2002FSNG4 is a particular type of battery charger that is designed to charge single-cell lithium-ion (Li-Ion) and LiPo batteries. It is a highly efficient, cost-effective, and reliable charger that can be used in a variety of applications.
BQ2002FSNG4 Application Field
The BQ2002FSNG4 is mainly used in consumer applications to charge small, portable electronic devices such as mobile phones, tablets, and GPS trackers. It is also used in backup power systems to provide power in the event of a power outage. Additionally, it can be used in a variety of automotive applications such as charging electric cars, charging on-board batteries, and providing backup power for motorcycles, ATVs, and boats.
BQ2002FSNG4 Working Principle
The BQ2002FSNG4 is a switch-mode charger, which means that it precisely controls the voltage, frequency, and waveform of the output current. Switch-mode chargers are more efficient than traditional linear chargers, as they use feedback technology to monitor the battery\'s status and adjust the output current as needed. This type of charging technology reduces the amount of energy and time required to charge the battery.
The BQ2002FSNG4 charger features a constant current/constant voltage (CC/CV) charging profile. This means that the charger begins by delivering a constant current to the battery, then when the battery is close to full capacity, it switches to a constant voltage output. This method of charging is the most efficient, as it ensures that the battery is completely charged without overcharging.
The BQ2002FSNG4 charger also includes a sleep mode, which is a low-power state that the charger enters when the battery is fully charged. This feature helps to conserve energy and extends the life of the battery, as it does not continuously draw power from the battery when it is already fully charged.
Conclusion
The BQ2002FSNG4 is a highly efficient, cost-effective, and reliable charger that can be used in a variety of applications. With its switch-mode technology and CC/CV charging profile, it is the perfect choice for charging small, portable electronic devices such as mobile phones and tablets. The BQ2002FSNG4 charger is specifically designed to be able to charge single-cell Lithium-ion and LiPo batteries safely and accurately. It is a great choice for backup power systems and automotive applications as well.
