STC3105
Battery monitor IC with alarm output for gas gauge applications-
NRND
The STC3105 battery monitor includes the hardware functions required to implement a low-cost gas gauge for battery monitoring. The STC3105 uses accurate measurements of the battery voltage to estimate a battery’s state-of-charge (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 calculation. The coulomb counter method is used for SOC tracking in high-load conditions.
An alarm output signals a low SOC condition, and can also indicate low battery voltage. The alarm threshold levels are programmable.
The device is programmable through an I2C interface.
