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.
