Overview
|
|
|
The NT1724 series are the 2-cell protection IC for lithium-ion/lithium-polymer rechargeable battery pack. The high accuracy voltage, current detector and delay time circuit are built in NT1724 series with state-of-art design and process.
To minimize power consumption, NT1724 series activates power-down function when an over-discharge event is detected (for power-down function “available” version). Besides, NT1724 series performs protection functions with six external components for miniaturized PCB. |
