GENERAL DEscriptION
The SGM41102/SGM41102A 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 SGM41102/SGM41102A integrates all the protections and the required low on-resistance disconnect switch on one die. The protection features include charge and discharge protection, detection and protection of a cell in over-charge, over-discharge, over-current, and battery under-voltage. The product also disconnects the battery pack in the case of deep discharge.
The SGM41102/SGM41102A operates in -40℃ to +85℃ temperature range, and is in a thin and low profile UTDFN-1.5×2-6L package. This package with a nominal height of 0.5mm is convenient for small cell packing designs.
