This reference design is a software implementation of a basic maximum power point tracking algorithm for a single-cell battery charging system using a solar panel input. This design removes the requirement for extra circuitry and complex firmware by using integrated features of the charger to achieve maximized charging current all through a simple I²C-based control scheme.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
