STEVAL-ISB011V1
Li-ion battery monitoring system demonstration board
based on the STC3100 and STM32
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
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.
Battery charging is performed using the USB port,
or using a DC adaptor.
