Wedoany.com Report, On March 4, 2026, Allegro MicroSystems, Inc., located in Manchester, New Hampshire, USA, announced the launch of the Hall-effect current sensor ACS37017. This high-precision magnetic current sensor is designed to meet the higher demands for power conversion efficiency in AI data centers, electric vehicles, and clean energy systems. With a typical sensitivity error of 0.55%, it provides a high-accuracy power sensing solution.
The ACS37017 is factory-calibrated, integrating high-voltage isolation and an advanced sensing architecture to ensure stable performance throughout its entire lifecycle and across operating temperature ranges. This product, together with Allegro's other two sensors, the ACS37100 and ACS37200, forms a comprehensive product matrix targeting speed, power density, and accuracy. The ACS37100, based on XtremeSense™ TMR technology, offers a 10 MHz bandwidth and is suitable for high-speed switching platforms. The ACS37200 excels in power density with its 50µΩ ultra-low conductor resistance.
Matt Hein, Director of the Current Sensor Product Line at Allegro MicroSystems, stated, "Our goal is to provide engineers with precise tools. The ACS37100 is suitable for fast fault detection, the ACS37200 optimizes space utilization, and the ACS37017 focuses on high-precision applications. We are committed to delivering leading sensing technology across all key areas." This high-precision magnetic current sensor employs a proprietary compensation architecture that effectively addresses drift issues caused by temperature changes or aging in traditional sensors, thereby improving long-term stability.
Furthermore, the ACS37017 simplifies system design by integrating a non-proportional voltage reference, eliminating the need for external precision components and reducing cost and layout complexity. Its compact packaging and high-voltage isolation features further enhance its applicability in electric vehicles and industrial systems. The launch of this high-precision magnetic current sensor provides more reliable feedback signals for high-voltage power conversion systems, supporting more efficient control loop operation.
