BQ24616RGER application field and working principle

PMIC stands for power management integrated circuit, and it plays an important role in the charging of batteries in many devices. The BQ24616RGER is a PMIC device that is specifically designed for the charging and protection of lithium-ion (Li-Ion) and lithium-ion polymer (Li-Poly) batteries. The device is a two-cell, single-ended parallel, battery charger that general applications that use Li-Ion/Li-Poly batteries can benefit from.The BQ24616RGER is a standalone battery charger, which means that it doesn’t require any external components for basic operation. It also includes several safety features to protect against short circuit, over-temperature, over-voltage and under-voltage conditions. This makes it suitable for applications that require a high level of reliability and safety.The BQ24616RGER is a dual-mode standalone charger input for both voltage and current sources. The input voltage range is from 4V to 9V, and the input current range can be as low as 8mA, making it suitable for portable applications that require an extremely low power profile or are powered by alternate sources. The charger is designed to provide a constant current/constant voltage charging process, with an adjustable charging current up to 1.1A. A built-in thermal regulation loop provides an accurate value of the battery temperature.The BQ24616RGER also integrates several additional features, such as over-charge and over-discharge protection, and over-temperature protection. It also provides auto-recharge and end-of-charge detection. This means that the charger can automatically detect when a battery is fully charged and shut off, eliminating the need for the user to manually disconnect the battery.Overall, the BQ24616RGER is a highly-integrated battery charging system with many built-in features that offer reliability and safety. It is designed to provide an efficient charging current to Li-Ion/Li-Poly batteries while protecting against over-temperature, over-voltage and under-voltage conditions. Additionally, the ability to accept input current down to 8mA makes it suitable for portable applications that require an extremely low power profile or are powered by alternate sources. This makes the BQ24616RGER an ideal solution for many applications.
