• Lack of adjustable voltage thresholds restricts customization options.

Working Principles

The S-8239AAI-M6T1U operates by continuously monitoring the voltage level of the connected battery. It compares the detected voltage with predefined thresholds for overcharge and overdischarge protection. When the voltage exceeds the overcharge threshold, the IC activates the overcharge protection mechanism, which can include actions like disconnecting the charging source. Similarly, when the voltage falls below the overdischarge threshold, the IC triggers the overdischarge protection mechanism, preventing further discharge. The enable control input allows users to enable or disable the functionality of the IC as required.
