LINEAR TECHNOLOGY  LT8490IUKJ#PBF  电池充电器, 铅酸, 锂离子, 锂聚合物电池, 80V输入, 80V / 10A充电, QFN-64

The 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 Li-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.
