Current Sensor ICs

Overview

The CQ2366 has a different package structure and different features than the other current sensors in the CQ2 series.
Instead of a magnetic core, it has a silicon steel plate, which enables it to measure larger current ranges than conventional models (±170A).
The primary conductor resistance of the CQ2366 is very low (100μΩ), like the other models in the CQ2 series. This makes it suitable for products which need to measure large currents while reducing heat generation.

The other CQ2 series have very different features. Please see this link.

This page contains information about the features of CQ2366, product details, datasheets, and product lineup information. It also provides technical information such as safety standard information and gerber data of evaluation board, etc.

Features

CQ2366

1. Low heat generation and High current capability

CQ2366 has a primary conductor resistance of 100μΩ (25°C) due to its unique AI-Shell package structure.Since the amount of heat generation is proportional to the resistance value, this enables it to minimize increases in temperature even when a large current is passed through it.

2. Measurement of large current ranges

The CQ2366 can be used for higher currents and stronger magnetic fields because its magnetic saturation point (a characteristic of magnetic materials) was raised by replacing its magnetic core with a silicon steel plate.
The CQ2366's current measurement range is more than triple that of the maximum effective current of 50Arms. This makes this current sensor highly suited for use in inverter control.

3. High accuracy / High resolution

The CQ2366 provides high accuracy and high resolution output, so it can be used where precise control is required.

High accuracy:Maximum Temperature Drift of Offset voltage  ±4mV
High resolution:Output Noise  0.5mVrms

Applications

  • General Inverter (Drives)  etc.
