Additional Details

The S-8211CAR-I6T1G features a built-in delay circuit to prevent false triggering of the protection functions due to transient voltage spikes or noise. The overcharge, overdischarge, and overcurrent detection thresholds are precisely calibrated to ensure accurate and reliable protection. The IC typically operates with a supply voltage in the range of 1.5V to 5.5V and is available in a small SOT-23-6 package. The specific overcurrent protection level depends on the external MOSFET used in the protection circuit. This IC is RoHS compliant, ensuring environmental responsibility.
