STEVAL-ISB017V1

Evaluation board includes the STMicroelectronics OptimGauge™ algorithm. It provides accurate battery state of charge (SOC) monitoring, tracks battery parameter changes with operation conditions, temperature and aging and allows the application to get a battery state of health (SOH) indication. An alarm output signals low SOC or low voltage conditions and also indicates fault conditions like a missing or swapped battery.

• Patented OptimGauge™ algorithm for accurate battery capacity calculation
• Robust initial open circuit voltage (OCV) measurement at power up
• Programmable low battery alarm
• Missing/swapped battery detection
• Average current internal calculation
• End of charge detection
• Internal temperature sensor
• Battery swap detection with protection against false battery insertion
• Low power 40µA in voltage only, 2µA max in standby mode
