KP235: Infineon's Next-Generation Coreless Current Sensor for High-Precision Applications

The demand for accurate and reliable current sensing technology continues to grow across various industries, from industrial automation and renewable energy to consumer electronics and automotive systems. Addressing this need, Infineon Technologies has introduced the KP235, a state-of-the-art coreless current sensor that sets a new benchmark for high-precision DC and AC current measurement.

Unlike traditional current sensors that rely on magnetic cores, the KP235 utilizes a coreless Hall technology. This design eliminates saturation effects and hysteresis, significantly enhancing linearity and accuracy. The sensor delivers exceptional performance with a total accuracy error of less than 0.9% across its entire operating temperature range. This makes it an ideal solution for applications where precision is non-negotiable, such as in servo drives, battery management systems (BMS), and solar inverters.

A key advantage of the KP235 is its ultra-low ohmic resistance of just 0.23 mΩ. This minimal internal resistance drastically reduces power loss and heat generation, leading to higher overall system efficiency. Furthermore, its compact and integrated package simplifies PCB design and saves valuable board space, which is crucial for modern, miniaturized electronics.

The sensor operates on a 3.3 V supply voltage and provides an analog output voltage proportional to the measured current. It is designed for a measurement range of up to ±50 A, offering both bi-directional and uni-directional current sensing capabilities. With built-in diagnostics and robust protection features, the KP235 ensures high reliability in demanding environments.

ICGOOODFIND: Infineon's KP235 represents a significant leap forward in current sensing technology. Its coreless design, combined with unparalleled accuracy and minimal power loss, provides engineers with a powerful and efficient solution for next-generation high-precision applications, enabling smarter and more energy-efficient systems.
