Allegro Introduces ACS37017 Sensor with 0.55% Accuracy for High-Voltage Systems
Allegro introduced the ACS37017 Hall-effect current sensor with 0.55% typical sensitivity error over lifetime and temperature, achieving industry-leading accuracy for high-voltage applications in AI data centers, xEVs, and clean energy systems. The device completes the strategic expansion of its power electronics lineup, offering integrated high-voltage isolation, low-drift compensation architecture, and embedded precision voltage reference to simplify system design and reduce bill of materials.
1. Product Launch and Accuracy Benchmark
Allegro has launched the ACS37017, a factory-calibrated Hall-effect current sensor delivering a typical sensitivity error of just 0.55% over lifetime and temperature. This level of precision establishes a new accuracy benchmark for high-voltage power conversion systems, enabling tighter control loops and enhanced efficiency in demanding applications.
2. Portfolio Expansion and Strategic Fit
The introduction of ACS37017 completes Allegro’s high-performance sensing toolkit alongside the ACS37100 for 10-MHz bandwidth speed and the ACS37200 for ultra-high power density. This strategic portfolio expansion ensures engineers have specialized solutions for speed, power density, or accuracy without compromise.
3. Technical Specifications and Design Benefits
The ACS37017 integrates reinforced high-voltage isolation and a proprietary low-drift compensation architecture to maintain stable measurements over temperature and lifetime. Its embedded precision voltage reference eliminates external components, reducing bill of materials, board space, and system-level noise.
4. Market Applications and Availability
Targeted at AI data centers, electrified vehicles, and clean energy systems, the ACS37017 addresses the rising demand for ultra-accurate current sensing in high-efficiency power converters. Engineers can request preliminary datasheets and engineering samples now through Allegro’s website.
