Overview
The NT1727 series is the 2-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 NT1727 series with state-of-the-art design and process. The NT1727 series have three types of discharge over-current protection and one type of charge over-current protection
Features
High accuracy voltage detection circuit Over-charge detection : ±25mV Over-discharge detection : ±80mV Discharge over-current-1 detection : ±10% Discharge over-current-2 detection : ±10% Load short-circuiting detection : ±10% Charge over-current detection : ±8mV/±10mV High withstand voltage Absolute maximum rating: 30V Operating voltage range: 3.5V to 12V Low power consumption Supply 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 function Package: 10 pin SOP Lead-free, Sn 100%, Halogen-free
Applications
Lithium-ion rechargeable battery pack Lithium-polymer rechargeable battery pack Lithium-iron phosphate rechargeable battery pack
