The MAX14578EWC+T device is part of the Power Management–Integrated Circuit (PMIC) family of ICs, specifically Battery Chargers. This IC offers a power solution specifically designed for portable, battery-powered applications, such as tablets, mobile phones, and laptop computers.The MAX14578EWC+T is a Li-Ion/Li-Polymer Battery charger, which is compliant with and certified for USB, USB On-the-Go (OTG) , Apple, and charger standards.

The MAX14578EWC+T is highly optimized for portability and offers a compact 48-BQFN package size, as well as a low operating current of 86microAmps. This IC offers a wide range of features that are designed to provide efficient, low-high current charging, as well as reliable over-temperature and over-voltage protection.

The MAX14578EWC+T provides a fast, efficient, and advanced charging sessions while charging one Li-Ion/Li-Polymer battery cell. This device is capable of stable, low-distortion, and low dropout current and can draw as much as 1000mA of current. It utilizes proprietary adjustable current limiting and thermal protection features to protect the device from over-temperature or over-voltage conditions.

The MAX14578EWC+T is offered in two versions: the MAX14578EWC, and the MAX14578EWT. The MAX14578EWC is specifically designed for sinewave or square wave input topologies, and the MAX14578EWT is specifically designed for switched capacitor buck battery charging applications. Both versions are thermal shutdown and current-limit protected from over-temperature and over-voltage conditions.

The MAX14578EWC+T’s principle application area is battery charging in portable devices. This device supports full, high-current charging voltage levels while input voltage is up to 5.0V. The IC also offers over-voltage protection, as well as short-circuit and constant current protection. It also can draw up to 1A of current, enabling fast charge times and short charging cycles, depending on battery capacity.

The MAX14578EWC+T also offers a built-in power path circuitry, allowing the device to handle a larger battery current range while enhancing the quality of the charging cycle. This device also integrates a programmable charge sequences, allowing users to select and adjust the battery charge parameters according to the user’s needs.

The MAX14578EWC+T also offers a power boost function for peak current charging. This feature allows the device to draw up to 1000mA of peak current from the battery without affecting the charging cycle. This feature preserves battery life during high-current charging, translating to a longer battery life in the device.

As a dedicated battery charger IC within the family of PMICs, the MAX14578EWC+T is designed for fast, accurate, and reliable battery charging. This device is optimized for a wide range of applications, providing an efficient and cost-effective charging solution for portable devices.
