ISL6256, ISL6256A is a highly integrated battery charger from Intersil. It has automatic power source selection function and can be used to power notebook computers.
The ISL6256 and ISL6256A are highly integrated battery‑charger controllers that use a synchronous buck topology and MOSFET‑based diode emulation to achieve high efficiency. They support automatic power‑source selection, allowing seamless switching between an AC adapter and the battery, and provide programmable charge‑voltage, current‑limit, and adapter‑current settings.
The datasheet includes functional block diagrams, typical application circuits, absolute‑maximum ratings, and detailed electrical specifications such as input voltage range, output regulation, and temperature limits. Package options (QFN and QSOP) and ordering information are also provided.
