Introduction

PMIC - Battery Chargers is a term used to describe Power Management Integrated Circuits (PMICs) used for charging batteries, such as Li-ion, Li-polymer and other batteries. Battery Chargers are considered to be a key component for most applications due to their safety and reliability. The BQ2002EPN is a PMIC specifically designed for battery sharing applications. It is a highly integrated PMIC that includes both an charger and a power supply. The BQ2002EPN is used in a wide range of applications, ranging from consumer electronics to industrial applications.

BQ2002EPN application field and working principle

The BQ2002EPN is used in many applications that require a reliable and safe way to charge batteries. It is used in many consumer electronics such as laptops, cell phones, tablets, and other personal electronics. It is also used in many industrial applications such as medical devices, military equipment, and other systems that need reliable charging to power their operations.The BQ2002EPN works by providing a constant current to the charged battery and by adjusting the supported voltage in accordance with the battery’s requirements. The constant current ensures that the battery is not overcharged while the adjustable voltage allows the battery to be fully charged without damaging it. The BQ2002EPN also provides protection against overvoltage, overheating, and short-circuit conditions. When the input voltage is above the regulation voltage, the BQ2002EPN will supply a constant current to the load. This allows the charged battery to be charged quickly and safely. When the input voltage reaches the regulation voltage, the BQ2002EPN will adjust its output to prevent the battery from becoming overcharged. This is done by setting the charge current such that the battery’s voltage is allowed to increase gradually and to not exceed the battery’s maximum voltage. When the input voltage is below the regulation voltage, the BQ2002EPN will disconnect the battery from the load and terminate the charging process. This prevents the battery from becoming overcharged and prevents any damage that could be caused by an overcharged battery.

Conclusion

The BQ2002EPN is a highly reliable and safe PMIC that is used to charge batteries in various applications. It provides protection against overvoltage, overheating, and short-circuit conditions, and it adjusts the supported voltage to ensure that the battery is not overcharged. The BQ2002EPN is a versatile PMIC that is suitable for a wide range of consumer and industrial applications.
