描述 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.

特性 Features

High accuracy voltage detection circuitOver-charge detection : ±25mVOver-discharge detection : ±80mVDischarge over-current-1 detection : ±10%Discharge over-current-2 detection : ±10%Load short-circuiting detection : ±10%Charge over-current detection : ±8mV/±10mVHigh withstand voltageAbsolute maximum rating: 30VOperating voltage range: 3.5V to 18VLow power consumptionSupply current: 6.6uA max. (Ta=+25℃)Delay times of over-charge, load short-circuiting are generated by an internal circuit (fixed).Delay times of over-discharge, discharge over-current-1 and 2 are controlled by external capacitors.Built-in breaking wire detector functionPackage: 10 pin SOPLead-free, Sn 100%, Halogen-free
