ST ISB011V1 User Manual

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

Data brief

STEVAL-ISB011V1

Battery charging is performed using the USB port, or using a DC adaptor.

■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 Liion batteries utilizing the highly-efficient gas gauge capability of the STC3100.
