SGMICRO SGM41100A-440O05YUDT6G/TR

The SGM41100 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 SGM41100 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 charge over-voltage, charge over-current, discharge under-voltage and discharge over-current. The product also disconnects the battery pack in the case of deep discharge.
• The SGM41100 operates in -40°C to +85°C 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.
