LT8491EUKJ#PBF

Switching Battery Charger Controller Lead-Acid/Li-FePO4/Li-Ion/Li-Pol 10000mA 1.3V to 80V 58-Pin QFN EP Tube

Analog Devices
Datasheets 

It operates from an input voltage that can be above, below or equal to the output voltage, making it ideal for use with a solar panel or a DC power source. Maximum power point tracking (MPPT) exacts the most power in solar applications. The LT8491 performs automatic temperature compensation by sensing battery temperature.

80V Battery Charger Optimizes Power Monitoring

  • • I2C Interface for accurate reporting of voltage, current, power and temperature
  • • Maximum Power Point Tracking for solar applications
  • • Buck-Boost topology allows for a wide input voltage range from 6 to 80V

Key Features and Benefits

  • • 80V Input Capability Allows for High Input Voltage Charging
  • • I2C Reporting with Graphical User Interface provides valuable information to the user
  • • Maximum Power Point Tracking allows for the maximum power to be extracted from the solar panel
  • • Buck-Boost Topology enables operation from a low input voltage down to 6V, ideal for Solar apps when shaded

Applications

  • • Building Infrastructure: Solar Panel charger for power grid applications
  • • Consumer: Escape Route Lighting/ Solar LED Lighting/ City Lighting/Parking/Traffic, e-bike charging station
  • • Energy: Solar Panel Charger applications, Solar Buoy/Telematics
