BQ24080DRCTG4 Application Field and Principles

The BQ24080DRCTG4 is a synchronous buck-boost DC/DC converter battery charger specifically designed for small and portable electronics. It is a high performance, power dense, and cost-effective one chip linear battery Charger. It is a single-chip current-mode synchronous boost DC/DC battery charger. This high density charger is designed to enable rapid charging of Li-Ion and Li-Polymer batteries.

The BQ24080DRCTG4 is intended for use in a wide range of applications and products, such as smartphones, tablets, wearables, handhelds, laptops, etc. It integrates MOSFETs, current and voltage protection, as well as power management. It also includes various safety features, such as thermal shutdown and overvoltage protection. The BQ24080DRCTG4 is a powerful solution for fast charging, high efficiency, and low power consumption.

Working Principles

The BQ24080DRCTG4 uses a synchronous buck-boost architecture, which allows it to operate from both input sources. When the input voltage is lower than the battery voltage, the charger will act as a synchronous buck converter. When the input voltage is higher than the battery voltage, the charger will act as a synchronous boost converter. The BQ24080DRCTG4 can work with input voltage between 6V and 32V, and is capable of charging either single cell or multiple cell Li-Ion/Li-Polymer batteries.

The BQ24080DRCTG4 uses current-mode control, which helps maintain constant current and voltage during charging. It also includes a low battery cutoff (LBC) function which automatically shuts down the battery when it is below the safe voltage level. It also has an adjustable input current limit and an adjustable charge current limit. This allows users to optimize the charge current to maximize charge efficiency while minimizing charge time.

The BQ24080DRCTG4 is designed to provide high efficiency and power density in a small package. It integrates a high performance integrated circuit, MOSFETs and current sense resistors into a small 4mmx4mm QFN package. The BQ24080DRCTG4 is a complete battery charging solution for portable devices, and its small size and low power consumption make it ideal for handheld devices and other battery-powered applications.

Safety Features

The BQ24080DRCTG4 includes several safety features to protect the device and battery from damage. When the battery voltage is over 4.2V, the charger will enter a hiccup mode until the voltage is below 4.2V, then resume charging. Overvoltage and overcurrent protection are also included to shut off the charger in the event of a fault condition. Additionally, the charger includes an adjustable thermal shutdown function to prevent the device from overheating.

The BQ24080DRCTG4 is a high performance, power dense, and cost-effective single-chip linear battery charger. It is designed with high efficiency and low power consumption in mind, and is well suited for use in a wide range of portable and mobile applications. It provides a complete solution for fast charging, and its safety features make it an ideal choice for many types of devices.
