Data Brief

Key Features

  • The STC3105 device uses the Coulomb counter method to track state-of-charge (SOC) or to track when the battery is charging or discharging
  • Accurate measurements of the battery voltage to estimate the battery state-of-charge
  • Battery parameters are sent to the PC via USB using a virtual COM port and can be observed using HyperTerminal as well as a GUI
  • The board can also display parameters on the LCD
  • Charging and discharging status is displayed by the + and - sign respectively on both the LCD and LED
  • The board also shows low voltage and SOC alarms
  • The board can monitor a battery with a capacity up to +/-10950 mAh
  • RoHS compliant
