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. It can be used for long term stocking and power recycling.
Charging a heavily depleted cell with too low or even zero voltage is allowed by SGM41105.
The SGM41105 is available in a Green XTDFN-1×1-4L package. It can operate (keep charge or discharge blocking) in the -40℃ to +85℃ ambient temperature range.
