STEVAL-ISB009V1

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 12bit to 14bit A/D converter. The battery current can be up to 2.5A and the accumulator system provides a capacity up to +/-7000mAh with a resolution of 0.2mAh. The device is programmable through an I2C interface.

• Accurate battery voltage measurement
• Coulomb counter to keep track of the battery’s state of charge
• Internal temperature sensor
• Internal or external 32KHz time base
• I2C interface for battery monitoring and device control
• Battery voltage accuracy of 0.5%
• Coulomb counter accuracy of 1% using an external RTC signal (3.5% using the internal time base)
• Low power consumption
