STC3117 - Gas gauge IC

General Description

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.

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 ma.

STC3117 Gas gauge IC with battery charger control for handheld applications CSP (1.49 x 1.594 mm) Datasheet - production data Description 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.
