BQ24105IRHLRQ1 can be classified as a PMIC (Power Management Integrated Circuit) - Battery Charger. It is a Constant-Voltage/Constant-Current linear charge management disconnect switch with integrated power MOSFETs and current sense resistor. The device is specifically designed for portable equipment that uses a rechargeable battery.

The main purpose of BQ24105IRHLRQ1 is to provide the system with power supply and charge to the battery. It integrates several components such as protection circuitry, current limit, thermal protection, and reverse current blocking. This allows the device to protect the system and the battery from over-voltage, under-voltage and over-temperature conditions.

BQ24105IRHLRQ1 is designed to provide increased battery capacity, charging current, and flexibility of charging algorithm. It is capable of providing up to 4 A current for charging, allowing for fast and efficient charging of the battery. The integrated circuitry eliminates the need for external discrete components, resulting in reduced design time and cost.

BQ24105IRHLRQ1 has two main components on board, called the Power Path Management Unit (PPMU) and the Battery Monitor and Management Unit (BMMU). The PPMU is responsible for regulating the charging current to the battery, and for monitoring its charge status. The BMMU is responsible for measuring the battery voltage, current, and temperature and for providing the necessary protection to prevent overcharging, overdischarging and overheating.

BQ24105IRHLRQ1 is ideal for powering portable devices such as mobile phones, tablets, wearables, and digital cameras. It is also suitable for automotive applications, such as smart home appliances and industrial equipment. This device can also be used in medical equipment, portable tools, and other devices.
