STC3117：Gas gauge IC with battery charger control for handheld applications
The STC3117 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.
Key Features
- 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: 40 μA in voltage-only mode, 2 μA max in standby mode
- 1.49 x 1.594 mm 9-bump CSP package
