The SGM41010 family are battery protection ICs for Li-Ion/polymer rechargeable batteries, including the high-accuracy voltage detection circuits and the delay circuits. The device is designed to protect 1-cell Li-Ion/ polymer rechargeable battery pack against over- charge, over-discharge and over-current.
The SGM41010 uses an external over-current detection resistor to achieve high-accuracy over- current protection with less effect from temperature change.
The SGM41010 is available in Green XTDFN- 1.4×1.4-6L and UTDFN-1.4×1.8-6L packages. It can operate in the -40℃ to +85℃ ambient temperature range.
