PMIC - Battery Chargers are essential components in any battery-driven system as they provide the required power to operate the system as well as ensure safety and reliability. The BQ24751RHDR is an advanced battery charging system designed to provide a robust, highly efficient, and reliable charging solution for portable applications. It is ideal for applications such as smart phones, tablets, digital cameras, MP3 players, and more.

The BQ24751RHDR is a highly integrated Li-ion battery charger with a host of features including high-efficiency power conversion, dynamic power management, and control over temperature and under/over voltage condition protection. It provides three programmable output current levels, making it well suited for a range of applications. It also includes highly integrated internal protection functions such as overvoltage protection, undervoltage lockout protection, short-circuit protection, and over-temperature protection.

The BQ24751RHDR features two programmable current limits - C/10(CC) and integrated output current limit. Its C/10 current limit is designed to restrict charging up to 10% of the rated battery capacity. The integrated output current limit allows the charger to be set to a desired current while still maintaining a regulated output voltage. This improves power efficiency in situations when a lower than rated current is needed.

The BQ24751RHDR also includes a comprehensive battery management system that works with the system\'s safety features to protect the battery. The system features a low dropout linear regulator that allows for robust battery management and a control loop for precise charging control. It also features a simple two-wire interface for communication between the system and the charger, eliminating the need for additional wiring. Additionally, the device also supports both constant voltage and constant current charging.

The BQ24751RHDR is a highly efficient power conversion device, enabling chargers to meet energy efficiency requirements without compromising performance. It features a high efficiency switch-mode converter, low power loss components, and a sophisticated digital control loop for regulating output. The digital control loop allow for precise charging control and accurate voltage regulation, allowing the user to precisely control the charging current and protect against overvoltage and undervoltage conditions.

The BQ24751RHDR is an ideal solution for portable device designers who need reliable and efficient battery charging. The high integration and efficient power conversion ensures device current loads are supplied with required power levels. The integrated battery management system and safety features help to keep the device and the battery safe, while the programmable current limits and two-wire communication interface makes it easy to manage battery charging.
