Description

The NT1715 series are the 1-cell protection IC for

lithium-ion/lithium-polymer rechargeable battery pack.

The high accuracy voltage, current detector and delay

time circuits are built in NT1715 series with state-of-art

design and process.

To minimize power consumption, NT1715 series

activate power down mode when an over-discharge

event is detected (for power-down mode enabled

version). Besides, NT1715 series perform protection

functions with five external components for

miniaturized PCB.

The tiny package is especially suitable for compact

portable device, i.e. slim mobile phone, tablet PC

battery packs, Digital camera and Bluetooth earphone.
