Power management integrated circuits (PMICs) are essential components for various applications, including mobile devices and industrial systems. The MAX6430EGUS+T is a PMIC specifically designed to provide advanced battery management for Li-ion/LiPo batteries. This device integrates a dedicated fuel gauge, temperature sensor,charger, and power supply in a single package, resulting in reduced system power and space requirements.

The main purpose of the MAX6430EGUS+T is to provide optimized battery charging and power-management features to ensure reliable operation in a variety of applications. It features a high-speed, highly accurate fuel gauge with advanced battery management features to monitor the cell voltage and current. Additionally, it contains a low-power temperature sensor to monitor the system temperature and act as an overheat protection. It also contains an internal power supply that provides power to the fuel gauge itself, and to the controller and external peripherals.

The MAX6430EGUS+T is well-suited for battery-powered applications, including mobile phones and other portable devices. Its fuel gauge can be integrated into the system host controller to provide accurate battery-status information. This information can be used to determine the battery charge level, remaining life, and temperature. The fuel gauge supports a wide range of rechargeable Li-ion/LiPo batteries and has a wide input range of 4.2–20V. This allows the device to work with small and large battery cells.

The MAX6430EGUS+T also provides a programmable digital charger with support for multiple battery chemistry types. The charger includes a safety timer, safety-related features, and programmable charge termination current, maximum current, and voltage. The digital charger has a wide input range of 5–25V and can charge single cell Li-ion/LiPo batteries up to 4.2V. It also includes power path management (PPM) to supply power to the load while simultaneously charge the battery.

The MAX6430EGUS+T provides power path management (PPM), allowing power to be routed from either the system power supply or battery, automatically switching between the two sources. This feature allows the system to operate on battery power if the system power is interrupted, ensuring the system remains operational. The device also provides hardware over-current protection and thermal-foldback shutdown protection.

Overall, the MAX6430EGUS+T provides a comprehensive solution for battery management in Li-ion/LiPo-powered applications. Its integrated fuel gauge, temperature sensor, and charger provide advanced battery management capabilities, while its power path management feature facilitates reliable system operation and increased safety. The device is well-suited for battery-powered applications, such as mobile phones and other portable devices.
