STC3105 - Battery monitor

Description

The STC3105 battery monitor includes the hardware functions required to implement a lowcost gas gauge for battery monitoring.

The STC3105 uses accurate measurements of the battery voltage to estimate a battery’s state-ofcharge (SOC).

Features

  • 0.5% accuracy battery voltage monitoring.
  • Low battery alarm output with programmable thresholds.
  • Low power: 60 µA in power-saving mode, 2 µA max in standby mode.
  • Ideal for implementation of robust gas gauge systems using open-circuit voltage and coulomb counter methods.
  • Small 3x2 mm package.
