STC3117 Datasheet, PDF (1/34 Pages) STMicroelectronics – Gas gauge IC with battery charger control for handheld applications

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.
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
Applications
• Mobile phones, multimedia players, digital
cameras
• Portable medical equipment
