Power management integrated circuit (PMIC) is a type of integrated circuit designed to manage different power management features in a system, providing power, signal conditioning, voltage regulation and protection for the system. PMICs are commonly used for mobile applications, industrial applications, consumer and automotive applications. One example of a PMIC is the BQ6400RGZR.

The BQ6400RGZR is a highly integrated single-cell Li-ion/Li-Polymer battery charger controller. It provides multiple levels of input currents, charge termination, charge regulation and safety features to protect the battery from overcharge, overdischarge and overheating. The device can be easily adapted to many applications through the use of pin-selectable options and is optimized for space-constrained applications.

The BQ6400RGZR has been designed primarily for use in battery management systems (BMSs). It is optimized for single-cell applications and is therefore used in products such as laptop computers, mobile phones and other small portable electronic devices. The device ensures the safe use and conservation of battery power by managing the charge and discharge of the battery in a regulated manner.

The BQ6400RGZR has a wide input current range (1.5A max) for multi-level charging of the battery and provides a variety of charge regulation features, including current regulation, voltage regulation, time regulation and temperature regulation. It also features an integrated amplifier for system feedback from the battery. The charge end-of-charge (EOC) indication is indicated via a status flag.

The BQ6400RGZR also has an integrated overvoltage and overcurrent protection circuit, to protect the battery from excessive charge/discharge currents. The device also provides an open-drain charge status pin to indicate the current charge status. Furthermore, the device includes an integrated Power Save Mode, which enables the system to increase battery life by periodically reducing the charge current and entering into the low-power mode.

The BQ6400RGZR is a highly integrated device with a wide range of features and is suited for applications that require optimized power management. Its efficient power management and protection features ensure safe and reliable battery charging, making it an ideal solution for single-cell Li-ion/Li-Polymer battery management systems.
