ANALOG DEVICES LT8490IUKJ#PBF Battery Charger IC, Lead Acid/Li-Ion/Li-Pol, 80 V, 1.3V to 80V/10 A Charge, -40 to 125 °C, QFN-EP-64

LT8490 is a buck-boost switching regulator battery charger that implements a constant-current constant voltage (CCCV) charging profile used for most battery types, including sealed lead-acid (SLA), flooded, gel and lithium-ion. This 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. This device 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. It is used in applications such as solar powered battery chargers, multiple types of lead-acid battery charging, Li-Ion battery charger, battery equipped industrial or portable military equipment etc.
