STEVAL-ISB011V1
Li-ion battery monitoring system demonstration board
based on the STC3100 and STM32
Data brief
Features
■
STC3100 uses Coulomb counter/gas gauge to
track the remaining charge in the battery, and
can read the charging current, temperature and
voltage of the battery
On-board STM32 microcontroller is interfaced
with USB, STC3100, LCD, switches. Battery
parameters are sent to PC via virtual COM port
Charging and discharging status displayed on
LCD.
Gas gauge: battery capacity up to +7300 mAh
can be monitored (programmable by user)
Supports external or internal battery charger
allowing evaluation of the STC3100 with the
user’s own charging system
On-board charger (STC4054) available to
charge the battery
Four switches for menu scrolling
Micro-USB B type connector can:
– communicate battery parameters to the PC
– provide power to the board
– charge the battery using internal charger
Option to interface external microcontroller
using jumpers
STC3100 clock source can be selected from
external oscillator, the device’s internal clock or
from clock generated by an internal/external
microcontroller
RoHS compliant
STEVAL-ISB011V1
Battery charging is performed using the USB port,
or using a DC adaptor.

Description
The STEVAL-ISB011V1 demonstration board is
based on the STC3100 battery monitoring device
and the STM32 microcontroller.
The STM32 microcontroller provides a simple,
compact solution to monitor the voltage,
temperature, current and capacity of single cell Li-
ion batteries utilizing the highly-efficient gas
gauge capability of the STC3100.
