Description
General part information
LT8491 Series
The LT8491 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.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 LT8491 can perform automatic temperature compensation by sensing an external thermistor thermally coupled to the battery. The STATUS pin can be used to drive an LED indicator lamp. The device is available in a low profile (0.75mm) 7mm × 11mm 64-lead QFN package.ApplicationsSolar Powered Battery ChargersMultiple Types of Lead-Acid Battery ChargingLi-Ion Battery ChargerBattery Equipped Industrial or Portable Military Equipment
