STC3117 Evaluation Board

STEVAL-ISB017V1

Overview

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.

Main features

Patented OptimGaugeTM 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, 2uA max. in standby mode
1.49 x 1.594 mm 9-bump CSP package
RoHS compliant

2014 Anhui Electric Competition Device Analysis and Forecast
Is there any expert who can help me analyze the direction of the 2014 Anhui Provincial Electrical Competition through devices? Thank you
TLP3547 Review
Previously, in the project test, it was necessary to cut off the power supply at a fixed time to verify the product's 200ms power-off switching capability. At that time, a 2A/DC 30V relay (Omron) was
