Description

Features and Benefits Product DetailsThe ADPS40099-RD is a fully integrated battery management system reference design suitable for portable applications. It consolidates a complete power solution for handheld and portable devices, utilizing the latest components from ADI’s power portfolio.The solution features the MAX77958 USB-C power delivery controller for flexible input options, paired with the MAX77786 1S battery charger to manage charging from a single-cell lithium-ion battery. The MAX17300 provides advanced fuel gauging, battery protection, and authentication capabilities, ensuring safe and reliable operation.To support diverse power requirements, the design includes the MAX77857 buck-boost regulator and the MAX77542 multi-phase buck converter, enabling up to five individually configurable outputs. The design also integrates the MAX14727 for power path control. For backup power, the MAX38889 utilizes supercapacitor technology to maintain system operation during power interruptions and battery replacements. Additionally, the MAX14611 logic-level translator ensures seamless communication between components operating at different voltage levels.This compact and cohesive single-board implementation offers a clear advantage in delivering a robust, space-efficient, and scalable battery management solution, ideal for modern portable electronic systems.
