Description

The NT1728 series is the 3-cell protection IC

for lithium-ion/ lithium-polymer/lithium-iron

phosphate rechargeable battery pack. The high

accuracy voltage, current detector and delay time

circuits are built in NT1728 series with

state-of-the-art design and process.

The NT1728 series have three types of

discharge over-current protection and one type of

charge over-current protection.

Features
