CQ-2332
High-Speed Small Current Sensor
1. Genaral Description
CQ-2332 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
- 5V 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)

These parameters can drift by the values in 14. Reliability Tests after the reflow and over the
lifetime of this product.
These parameters are guaranteed by design.
Total accuracy ETO is calculated by the equation below.
ETO = |100 × (Vh_meas − Vh) / Vh| + |100 ×(Vof_meas − Vof_meas_35) / (Vh × |INS| × 2)| + |ρmeas|
where Vh_meas[mV/A], Vof_meas[mV], ρmeas[%F.S.] represent the measured value of sensitivity, offset
voltage and linearity error respectively, Vh[mV/A] represent the typical value of sensitivity, and
Vof_meas_35[mV] represent the measured value of offset voltage at Ta = 35C. In the case of
CQ-2332, ETO is calculated by the equation as below.
ETO = |100 × (Vh_meas − 100) / 100| + |100 ×(Vof_meas − Vof_meas_35) / (100 × 21 × 2)| + |ρmeas|
