Additional Details

The S-8211CAW-I6T1U integrates a high-accuracy voltage detection circuit for overcharge and overdischarge protection. It also includes a current sensing circuit to detect overcurrent conditions. When an abnormal condition is detected, the IC disables the charging or discharging path to protect the battery. The IC features low current consumption in both active and standby modes, which helps to prolong the battery's operating time. The overcharge detection voltage is typically 4.2 V and overdischarge detection voltage is typically 2.4 V. The operating temperature ranges from -40°C to +85°C. It is available in a small SOT-26 package. The protection functions are crucial for maintaining the battery's health and preventing potential hazards in portable electronic devices.
