0 to 400 A Current Sensor ICs with Integrated Conductor

We drive innovation in the current sensor industry with a history of first-to-market products that give our customers a competitive edge. Did you know we invented the 100 µΩ CB package with high isolation for sensing up to 400 amps? It offers world-leading efficiency and power density.

Our high current sensor IC packages are fully integrated solutions that also provide high accuracy and reliability. These sensors are automotive-grade devices that can take the heat and deliver highly accurate open-loop current sensing in the harshest applications environments.
