Current Sensor

Product Description

The iCS121 Linear Current Sensor IC from inergy Technology is a state-of-the-art, economical, and precise solution for AC/DC current sensing, perfect for both industrial and consumer applications. By integrating a high-accuracy Hall sensor, the iCS121 can accurately measure the current flowing through the primary conductor and convert it into a proportional voltage output, offering exceptional precision.

This bi-directional current sensor operates with galvanic isolation between the primary current conductor and the secondary sensor, ensuring safe and reliable current measurement for both high-side and low-side applications. The sensor is ideal for applications where low power consumption and fast response times are essential, such as in Wide Bandgap (WBG) power devices and motor control systems.

Featuring a 1.2 mΩ primary conductor resistor, the iCS121 is designed to minimize power losses, making it significantly more efficient compared to traditional current sensing methods. Additionally, with a high-speed response time of less than 1 microsecond, this sensor is well-suited for the latest power electronics technologies.

Its compact footprint ensures ease of integration into space-constrained designs, making it an ideal choice for everything from power management systems to renewable energy applications.
