STEVAL-ISB013V1
Description
The STEVAL-ISB013V1 is a demonstration board
based on the STC3105 battery monitor IC. The
application monitors the voltage and current of a
battery and includes a Coulomb counter to keep
track of the charge/discharge status.
An alarm output signals a low state-of-charge
(SOC) condition and/or low battery voltage. In
addition, a relaxation register begins counting
when the gas gauge is in a specified light-load
condition, indicating when an OCV (open circuit
voltage) measurement should be made for SOC
correction.
