Shunt-basesd current sensor

The Isabellenhütte ICD Series is a high-precision digital current measurement module designed to provide accurate, real-time monitoring of direct currents in both unidirectional and bidirectional systems. Housed in a compact and robust package, the ICD integrates a shunt-based sensing element, a 16-bit Sigma-Delta analog-to-digital converter (ADC), and advanced signal processing capabilities to deliver high-resolution current, voltage, and temperature readings. It is optimized for applications requiring fast and reliable feedback over a CANbus 2.0A/B interface, supporting transmission rates up to 1 Mbit/s.

The device is engineered for use in harsh electrical environments, with an input voltage range from 5.5 V to 26 V, and operational ambient temperatures from -40°C to +105°C. It measures current ranges up to ±500 A, with overcurrent events detectable up to 2500 A, making it suitable for high-load systems. The sensor also supports multiple programmable features, including filter settings, measurement intervals, wake-up thresholds, and sleep mode behaviors, enhancing its adaptability across various applications.

All measurement and diagnostic data—including internal temperature, supply voltage, and device status—are digitally accessible, offering system designers a complete power monitoring solution in a single, integrated component. The ICD Series is particularly well-suited for precision current measurement in automotive electrification, industrial energy systems, and battery-powered platforms where space, accuracy, and digital communication are critical.
