80V BUCK-BOOST CHARGING CONTROLLER WITH MPPT FOR SOLAR PANELS

The LT8491 from Analog Devives includes Maximum Power Point Tracking (MPPT) for solar panels, with algorithms, lead acid and lithium ion batteries up to 80V.

Analog Devices (ADI) has introduced aΒ buck-boost Maximum Power Point Tracking (MPPT)Β battery charging controller that includes algorithms for charging sealed lead acid, gel and flooded cells, and Li-Ion batteries up to 80V alongside a solar panel.

Features:

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

TheΒ LT8491Β includes MPPT,Β temperature compensation and I2C interface for telemetry and control. It operates from input voltages above, below or equal to the regulated battery float voltage with three selectable Constant Current Constant Voltage (CC-CV) charging profiles, making it suitable for charging a variety of battery chemistry types including sealed lead acid, gel and flooded cells, and Li-Ion. All charge termination algorithms are provided onboard, eliminating the need for software or firmware.
