The BQ24158YFFT charge management device integrates multiple power management functions along with full system control functions in a single package. It also provides a wide range of features and protection features such as input overvoltage protection and an automatically adjustable charging current limit.

The BQ24158YFFT belongs to the PMIC (Power Management IC) family of products, and is classified as a Battery Charger. Battery Chargers are used in chargers and power supplies for mobile phones and similar portable devices, with the BQ24158YFFT charger being designed for ultra-low power applications. The BQ24158YFFT charger provides several important functions including providing a regulated power backup, over current and over voltage protection, and integrating a 7-bit MCU for system control.

The working principle of the BQ24158YFFT Battery Charger is based on the stepped charging principle. The charge cycle starts when the power supply is connected and the charger detects power. The charger then begins to draw current to charge the battery. During this stage, the charge current increases gradually. When the battery reaches a predetermined level, the charger reduces the current and the voltage gradually to ensure a controlled and safe charging. Finally, when the charging is completed, the charger stops charging and the system enters into a standby mode.

The BQ24158YFFT Battery Charger provides a great solution for applications where ultra-low power, high efficiency and system control are required. This charger can be used in notebooks, mobile phones, GPS devices and similar small portable devices. It provides all the features and protection necessary to ensure a safe, reliable and efficient charging process.

The BQ24158YFFT Battery Charger is designed with advanced technologies such as SMBus communication for monitoring and controlling the charge process. The integrated MOSFETs enable high efficiency even at very low current levels, reducing power dissipation and optimizing the battery life. Some of the additional features include thermal protection, LED indicator and vibration sensing.

In summary, the BQ24158YFFT Battery Charger is an ideal power management IC for ultra-low power applications, and is designed for use with notebook computers, mobile phones, GPS devices and similar small portable devices. The integrated features and protection provide a safe, reliable and efficient charging process, and the SMBus communication enables advanced and fine-grained control over the charge process. With its low power features, advanced features, and wide array of protection features, this charger is without a doubt one of the best solutions for ultra-low power applications.
