GENERAL DEscriptION

The SGM4064 is designed for front-end protection of Li-Ion battery charger.

The SGM4064 works like a linear regulator, and constantly monitors the input voltage and battery voltage to maintain an output voltage of 5.1V, and the input voltages reach the input over voltage threshold (VOVP = 6.8V).

The SGM4064 has temperature monitoring function. When the temperature exceeds 145℃, the device will switch off. The SGM4064 provides a fault status indication when it is controlled by the processor.

The SGM4064 is available in a Green TDFN-2×2-8L package and is rated over the -40℃ to +85℃ temperature range.
