Overview
The NT1758 is the 1-cell protection IC for lithium-ion/lithium-polymer rechargeable battery pack. The high accuracy voltage detector and delay time circuits are built in NT1758 with state-of-art design and process. 

To minimize power consumption, NT1758 activates power down mode when an overdischarge event is detected (for power-down mode enabled version). Besides, 

NT1758 performs protection functions with four external components for miniaturized PCB. 
The tiny package is especially suitable for compact portable device, i.e. slim mobile phone and Bluetooth earphone.
