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 DevicesIt 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
