PCIM Europe 2026, a premier global power electronics event, has concluded in Nuremberg, Germany. Xichan Microchip Sensors unveiled its innovative solution that integrates high-precision Hall current sensor chips into IGBT power modules for the first time. Adopting die-level precise calibration and in-depth module integration, the solution features a compact size of merely 5 millimeters while enabling accurate control over power up to 500 kilowatts. It pioneers a new paradigm for current sensing in automotive and industrial sectors, drawing extensive attention and cooperation discussions from numerous world-renowned automakers.

The solution is developed with three core objectives: cost optimization, user-friendliness and high reliability:

• Cost efficiency: Leveraging the high-precision direct transverse magnetic field measurement principle, it eliminates conventional magnetic cores and completely removes hysteresis effects, with theoretically no upper limit on current. Its miniaturized packaging also delivers a more compact and flexible system design.

• Ease of use: Combined with non-magnetic design for long-term operational stability, the sensor greatly simplifies maintenance and extends equipment service life.

• Reliability: Certified to AEC-Q100 standards, it fully adapts to the harsh operating conditions of automotive and industrial applications.

  
  

The breakthrough is underpinned by Xichan Microchip Sensors’ self-developed patented technology — Backside Vertical Hall Sensing Technology. This technology allows the chip to accurately capture transverse magnetic fields. Compared with traditional solutions, it fundamentally eliminates hysteresis and saturation effects, while boasting higher sensitivity to transverse magnetic fields.

Apart from improved measurement accuracy, this advancement also enables more compact and flexible integration for scenarios requiring vertical magnetic field detection, such as current monitoring and angle sensing. Xichan Microchip Sensors also showcased a full lineup of sensing products for automotive and industrial applications. Alongside the integrated solution, products including the S4-3DB01 magnetic position sensor and S4-CSA02 current sensor were on display, demonstrating comprehensive full-scenario sensing capabilities covering position and current detection.    

The debut at PCIM Europe 2026 marks a crucial milestone for Xichan Microchip Sensors in the field of power module integration. Going forward, the company will continue to deepen its research into automotive-grade magnetic sensing technology and drive the intelligent and integrated upgrading of power modules.
