Additional Details

The S-8240AAT-I6T1U provides comprehensive protection for lithium-ion batteries. The overcharge protection feature prevents the battery voltage from exceeding a safe level during charging. The overdischarge protection feature prevents the battery voltage from dropping below a safe level during discharging. The overcurrent protection feature limits the discharge current to a safe level. The short-circuit protection feature immediately shuts off the discharge path in the event of a short circuit. The device uses highly accurate voltage detection circuitry to ensure reliable protection. This protection IC operates typically within a temperature range of -40°C to +85°C. The overcharge detection voltage is typically around 4.2V, and the overdischarge detection voltage is typically around 2.4V, but these values depend on the specific model within the S-8240 series.
