Maximum Power Point Tracking Algorithm for Low Power Solar Battery Charging Reference Design
Description
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.
Features
