Product Overview

The LT8490EUKJ#PBF is a high current Buck-Boost Battery Charge Controller with maximum power point tracking (MPPT). It 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 LT8490 can perform automatic temperature compensation by sensing an external thermistor thermally coupled to the battery. STATUS and FAULT pins containing charger information can be used to drive LED indicator lamps. Many battery charging applications can be implemented using one of the reference applications with little or no modification required. Configuration for the various charging parameters is implemented in the hardware.
  • 6 to 80V VIN range
  • 1.3 to 80V VBAT range
  • Single inductor allows VIN above, below or equal to VBAT
  • Automatic MPPT for solar powered charging
  • Automatic temperature compensation
  • No software or firmware development required
  • Operation from solar panel or DC supply
  • Input and output current monitor pins
  • Four integrated feedback loops
  • 100 to 400kHz Synchronizable fixed frequency
