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
