The is a high current Buck-Boost Battery Charge Controller with maximum power point tracking MPPT. It implements a constant-current constant-voltage CCCV charging profile used for most battery types, including sealed lead-acid SLA, flooded, gel and lithium-ion. The device operates from input voltages above, below or equal to the output voltage and can be powered by a solar panel or a DC power supply. On-chip logic provides automatic maximum power point tracking MPPT for solar powered applications. The LT8490 can perform automatic temperature compensation by sensing an external thermistor thermally coupled to the battery. STATUS and FAULT pins containing charger information can be used to drive LED indicator lamps. Many battery charging applications can be implemented using one of the reference applications with little or no modification required. Configuration for the various charging parameters is implemented in the hardware.
