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.
