CQ36 Series of Asahi Kasei Microdevices Corporation (AKM) is a digital output current sensor IC with a Delta-Sigma modulator. It utilizes Hall elements made of III-V compound semiconductors, achieving the accuracy comparable to a current detection solution using a shunt resistor and isolated ADC. This results in reduced component count, smaller package size, and lower heat generation, contributing to the miniaturization of industrial equipment systems.


By integrating the current sensor and Delta-Sigma modulator into a single chip, the required peripheral components are reduced to the minimum, contributing to system downsizing. Additionally, the CQ36 Series is extremely thin compared to cement resistors, allowing for reflow installation and increased layout flexibility.

By utilizing III-V compound semiconductors, the CQ36 Series achieves ENOB: 12-14bit, providing high resolution comparable to current sensors that use a shunt resistor.

Its unique packaging development enables a low primary resistance of "0.27mΩ." This significantly suppresses the heat generation during the current application compared to the shunt resistors and similar products, allowing for continuous current flow up to 60Arms.

Through unique packaging development, surface distance and spacing of ≥ 8mm are achieved.

With a working voltage exceeding 550Vrms, it can be used in reinforced insulation for 400V systems.
