STEVAL-ISB011V1, Li-Ion battery monitor and gas gauge
based on the STC3100
Introduction
This document describes an easy and compact solution to monitor voltage, temperature,
current, and capacity of single cell Li-Ion batteries using the STC3100, which has a highly
efficient gas gauge. In addition, the board has an internal charger in order to charge the
battery. Battery charging can be done through the USB port or by using a DC adaptor.
The board has the following devices:
■ Battery monitoring device STC3100
■ Microcontroller STM32F102C6
■ Voltage regulator LD1117Axx33
■ Li-Ion battery charger IC STC4054
■ Step-up converter L6920
