Overview

[CQ-206B] CQ-206B High-Speed Small-Sized Current Sensor Overview CQ-206B is an open-type current sensor using a Hall sensor which outputs the analog voltage proportional to the AC/DC current.

Quantum well ultra-thin film InAs (Indium Arsenide) is used as the Hall sensor, which enables the high-accuracy and high-speed current sensing.

Simple AI-Shell package with the Hall sensor, magnetic core, and primary conductor realizes the space-saving and high reliability.

Key Features

  • - Unidirectional type - Electrical isolation between the primary conductor and the sensor signal - 5V single supply operation - Ratiometric output - Low variation and low temperature drift of sensitivity and offset voltage - Low noise output: 2.1mVrms (max. ) - Fast response time: 1μs (typ. ) - Small-sized package, halogen free Functional Block Diagram P Magnetic Core Amplifier Buffer VOUT Hall Sensor Compensation VSS Bias Unit EEPROM Unit VDD DATA_IO SCLK N Figure 1.
