Features ?? High Detection Accuracy ?? Overcharge Detection: ±25mV ?? Overdischarge Detection: ±50mV ?? Discharge Overcurrent Detection: ±15mV ?? Charge Overcurrent Detection: ±30mV ?? High Withstand Voltage ?? Absolute maximum ratings: 28V (V- pin and CO pin) ?? Ultra Small Package ?? SOT-23-5 ?? SOT-23-6 ?? DFN-6L Description The NT1702 series are 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 NT1702 series with state-of-art design and process. To minimize power consumption, NT1702 series activates power down mode when an overdischarge event is detected (for power-down mode enabled version). Besides, NT1702 series 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. Application ?? Mobile phone battery packs ?? Digital camera battery packs ?? Bluetooth earphone Li-ion battery module
