Magnetic Coreless Current Sensor "Currentier"

Magnetic Coreless Current Sensor "Currentier"

A low-heat current sensor that contributes to the miniaturization of substrates!

"Currentier" is a magnetic coreless current sensor IC equipped with a high-sensitivity Hall element. Despite being a coreless type, it achieves high precision comparable to that of closed-loop systems. Compared to conventional shunt methods, it has the following advantages: 1. The resistance value of the primary conductor is low at 0.27mΩ (which helps suppress heat generation), 2. The primary side does not require a power supply, allowing for a significant reduction in board size. Additionally, by offering a wide range of current options in the same package across the series, it enables the standardization of components and boards. 【Features】 - Capable of continuous high current operation (50/60/100A) - Creepage/clearance distance: ≧8mm (in compliance with UL61800-5-1) - Safety standards: UL1577 and IEC/UL62368-1 certified - Overall accuracy: ±0.4% F.S. (Ta=0~90℃ Typ.) *CZ370x series - Response time: 1μs Typ. *CZ370x series - Built-in disturbance magnetic field suppression function *For more details, please refer to the PDF documentation or feel free to contact us.

High-speed response compact/thin current sensor "CZ3Axx series"

High-speed response compact/thin current sensor "CZ3Axx series"

Contributing to the improvement of system safety! Coreless current sensor with built-in high-speed, high-precision overcurrent detection function.

CZ3Axx is a magnetic coreless current sensor with built-in Hall elements and overcurrent detection functionality. It achieves a high-speed response of 1μs and high precision of 0.3% F.S., enabling the detection of various fault modes such as ground faults and arm short circuits, contributing to improved system safety. Additionally, through its unique packaging technology, it realizes a low primary conductor resistance of "0.27mΩ" and high insulation with a creepage/clearance distance of ≧8mm. This significantly reduces heat generation during current application compared to shunt resistors, and eliminates the need for a primary side power supply or amplifier for insulation, allowing overcurrent detection with just the IC. Therefore, it can be placed in limited spaces on a circuit board. *For more details, please refer to the PDF document or feel free to contact us.
