bq24210EVM-678 Solar Battery Charger

Texas Instruments' 800mA, single-input, single cell Li-ion solar battery charger

Image of Texas Instruments' bq24210EVM-678 Solar Battery ChargerTexas Instruments' bq24210EVM-678 assists users in evaluating the bq24210 solar charger. The bq24210 is a highly integrated Li-ion linear charger targeted at space-limited portable applications. The high input voltage range with input over-voltage protection supports low-cost unregulated adapters. The input voltage regulation loop with programmable input voltage regulation threshold make it suitable for charging from alternative power sources, such as solar panel or inductive charging pad. The IC has a single power output that charges the battery. A system load can be placed in parallel with the battery as long as the average system load does not keep the battery from charging fully during the ten hour safety timer. 

Features
  • Input voltage dynamic power management feature (VBUS_DPM)
  • Selectable battery tracking mode to maximize the charge rate from solar panel using DPM feature
  • Load mode to support loads connected at VBUS pin
  • 20V input rating, with over-voltage protection (OVP)
  • 1% battery voltage regulation accuracy
  • Up to 800mA charge current with 10% charge current accuracy
  • Thermal regulation protection for output current control
