STC3105 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). It uses a low cost sense resistor to precisely sense the charge or discharge states, detect light-load conditions without ambiguity for voltage measurements, and accurate SOC...
