Power Management Integrated Circuits (PMICs) are the building blocks of integrated power systems. They provide the means to distribute, regulate, monitor, and optimize the electrical power within a system. PMICs can be found in many industries, from consumer electronics to industrial automation. Battery charging is one of the most important applications of PMICs. The FAN5403BUCX is one such PMIC designed to provide high efficiency and fast charging for Li-ion/ Li-polymer battery packs.

The FAN5403BUCX is a single-channel linear Li-ion/ Li-polymer battery charger that is available in a 4 mmx3 mm DFN package. It is optimized for lithium battery packs with up to four cells in series. The FAN5403 is capable of providing an output current of 600mA, making it suitable for rapid charging applications. The charger features a constant current/constant voltage architecture, as well as various safety features to prevent over-charging of the battery. The device also has a built-in temperature monitor to ensure safe charging over a wider temperature range.

The FAN5403 is designed to work at a wide range of input power sources. It features an adjustable input voltage range from 6V-26V, making it suitable for a variety of input sources, such as USB ports and wall adapters. The charger also has an integrated Power Path Management (PPM) function, allowing it to automatically switch between USB and an AC/DC power source, while still providing continuous charge current. This ensures that the battery is always charged, even if the USB power source suddenly drops or fails.

The FAN5403 also has a programmable charge current level and three access modes. The programmable charge current allows the user to set the desired output charge current, thereby enabling the charging process to be optimized to the desired performance parameters. The three access modes are direct charging mode, in which the device directly charges the battery with a constant current/ constant voltage algorithm; pre-charge mode, in which the device first charges the battery at a low current level; and trickle charge mode, in which the device maintains a low charge current to the battery. Furthermore, the device offers built-in protection features, including over-voltage, over-temperature, and over-current protection.

In summary, the FAN5403BUCX is an ideal solution for rapid charging applications. Its high efficiency and wide range of features make it a great choice for Li-ion/ Li-polymer battery packs. It provides a high input voltage range, a programmable charge current, and built-in protection features that make it suitable even in the most demanding applications. Its integrated PPM functionality ensures that the battery is always being charged, even when the USB power source fails. The FAN5403BUCX is a great choice for any application where fast and safe charging of Li-ion/ Li-polymer battery packs is required.
