STC3105 Battery monitor

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). It uses a low cost sense resistor to precisely sense the charge or.
