CQ-2234

[CQ-2234] CQ-2234 High-Speed Small Current Sensor 1. Genaral Description CQ-2234 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. 2. Feartures - Bidirectional type - Electrical isolation between the primary conductor and the sensor signal - 3.3V single supply operation - Ratiometric output - Low variation and low temperature drift of sensitivity and offset voltage - Low noise output: 1.2mVrms (typ.) - Fast response time: 1μs (typ.) - Small-sized package, halogen free - Standards: IEC/UL 60950-1, UL 508, CSA C22.2 No. 14 IEC 62109 (certification pending) MS1568-E-01 -1- 2014/04 [CQ-2234] 3.
