Abstract

This application note outlines the design of a high-power supercapacitor backup system using the BQ25822 charger IC. Key considerations such as system load management, charge current control, and converter efficiency are addressed to verify reliable and efficient operation. Test results confirm the BQ25822 as a preferred design for high power supercapacitor-based backup applications.
