SGM41105 Primary Protector and Switch with Shipping Mode for Tiny Li+/Poly Battery GENERAL DESCRIPTION The SGM41105 is a monolithic primary protector device for small Li-Ion or Li-Ion polymer battery 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. A bi-direction blocking switch is integrated with all essential protection functions for safe operation of the battery cell, including two for voltage abnormalities and three for currents. As a battery switch, external input is provided to set or release off-state.
