In this application report, Texas Instruments describes a solution to track the maximum power point of a solar panel using a negative temperature coefficient (NTC) thermistor with the bq24650. The basic functionality of a solar panel is described. The use of a spreadsheet tool to aid in the setup process is described as well.

The bq24650 is a switch-mode, battery charge controller that is capable of using a solar panel as the input power source. The bq24650 has the ability to aid in tracking the solar panel's maximum power point with the use of the MPPSET pin. This document shows the typical application circuit of the bq24650 controller.
