LT8491 Datasheet High Voltage Buck-boost Battery Charge Controller

Manufacturer: Analog Devices

Overview: LT8491 High Voltage Buck-Boost Battery Charge Controller with Maximum Power Point Tracking (MPPT) and.

General Description

The LT®8491 is a buck-boost switching regulator battery charger that implements a constant-current constantvoltage (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.

Key Features

  • n VIN Range: 6V to 80V n VBAT Range: 1.3V to 80V n Single Inductor Allows VIN Above, Below, or Equal to VBAT n Automatic MPPT for Solar Powered Charging n Automatic Temperature Compensation n I2C Telemetry and Configuration n Internal EEPROM for Configuration Storage n Operation from Solar Panel or DC Supply n Four Integrated Feedback Loops n Synchronizable Fixed Frequency: 100kHz to 400kHz n 64-Lead (7mm × 11mm × 0.75mm) QFN Package.
