CQ-2235
High-Speed Small Current Sensor
1. Genaral Description
CQ-2235 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)
