Descriptions
The NT1721 protects lithium-ion/lithium-polymer
rechargeable battery in the event of overcharge,
overdischarge and discharge overcurrent for a
2-serial-cell lithium-ion/lithium- polymer battery pack.
The NT1721 contains high-accuracy voltage detection
circuits and delay circuits.
If any of the above abnormal conditions occur. NT1721
will turn off its external MOSFETs to protect the battery
pack.
NT1721 will enter into power down mode when
overdischarge protection occurs to minimize the
current consumption.
NT1721 will charge the external capacitor for delay
time control.
The 0 V battery charging function is available for
Applications NT1721 by customer’s request.
