STEVAL-ISB009V1

Li-Ion battery monitoring and gas-gauge demonstration board

based on the STC3100

Features

■ Accurate battery voltage measurement

■ Coulomb counter to keep track of the battery’s

state-of-charge

■ Internal temperature sensor

■ Internal or external 32 kHz time base

■ I2C interface for battery monitoring and device

control

■ 0.5 % battery voltage accuracy

■ 1 % Coulomb counter accuracy using an

external RTC signal (3.5 % using the internal

time base).

■ Low power consumption: 100 µA in operating

conditions, 2 µA in stand-by mode

■ RoHS compliant

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.

The device is programmable through an I2C

interface.
