Description

The STEVAL-ISB009V1 demonstration board,

based on the STC3100, is able to monitor the

critical parameters of a single-cell Li-Ion battery

(voltage, temperature, and current) and includes

hardware functions to implement a gas-gauge for

battery charge monitoring, based on a

programmable 12-bit to 14-bit A/D converter.

The battery current can be up to 2.5 A and the

accumulator system provides a capacity up to +/-

7000 mAh with a resolution of 0.2 mAh.
