The SGM41107 is designed for primary protection of Li-Ion/polymer rechargeable cells. The product integrates all the protections required for safe operation of polymer rechargeable cells. The device is packaged in a tiny and thin package. Its small solution size leaves more space for fitting the battery cell into a given cavity for small size wearable devices.
The SGM41107 integrates all the protections and the required low on-resistance disconnect switch on one die. The protection functions include charge and discharge protection, mainly detecting and protecting battery over-charge, over-discharge and over-current. The product also disconnects the battery pack in the case of deep discharge.
The SGM41107 operates in -40℃ to +85℃ temperature range, and is in a thin and low profile XTDFN-1×1-4L package. This package with a nominal height of 0.37mm is convenient for small cell packing designs.
