GENERAL DEscriptION
The SGM41101 is designed for primary protection of Li-Ion/Li-polymer rechargeable cells. The product integrates all the protections required for safe operation of polymer rechargeable cells. The device is packaged in a thin package. Its small solution size leaves more space for fitting the battery cell into a given cavity for small size wearable devices.
The SGM41101 integrates all the protections and the required low on-resistance disconnect switch on one die. The protection features include charging and discharging protection, detection and protection of a cell in over-charging, over-discharging, over-current, and battery under-voltage. The product also disconnects the battery pack in the case of deep discharge.
The SGM41101 operates in -40℃ to +85℃ temperature range, and is in a thin TDFN-2×2-6L package. This package with a nominal height of 0.75mm is convenient for small cell packing designs.
