Allegro MicroSystems announced the launch of its ACS37017 Hall‑effect current sensor on February 10, 2026, completing a three‑product lineup that now covers speed, power density, and accuracy for modern power‑electronics applications.
The new sensor delivers a typical sensitivity error of 0.55% over its lifetime and operating temperature range, incorporates high‑voltage isolation, and uses a proprietary compensation architecture that keeps drift minimal. Its integrated non‑ratiometric voltage reference eliminates the need for external precision references, reducing bill‑of‑materials costs and board space for customers.
By adding an accuracy‑focused option, Allegro addresses a key demand in AI data centers, electrified vehicles, and clean‑energy systems—markets that increasingly require precise current measurement to improve efficiency and reliability. The ACS37017 complements the high‑speed ACS37100 and the high‑density ACS37200, positioning Allegro to compete with industry players such as Honeywell, TDK, and Infineon in the high‑accuracy sensor segment.
Allegro’s recent financial performance underscores the strategic importance of the launch. In the third quarter of fiscal 2026, the company reported sales of $229 million, up 29% year‑over‑year, and a non‑GAAP EPS of $0.15, a 114% increase from the prior year. Growth was driven by strong demand in the e‑Mobility and Industrial & Other segments, reflecting the company’s expanding footprint in high‑growth markets.
Matt Hein, Business Line Director of Current Sensors, said, “Our philosophy is simple: we want to give engineers the right tool for the job.” The quote highlights Allegro’s focus on tailored solutions that meet specific engineering challenges.
The global current‑sensor market is projected to grow from $2.18 billion in 2023 to $4.24 billion by 2030, at a CAGR of 10.1%. Demand is being driven by the rise of electric vehicles, industrial automation, and renewable‑energy deployments—trends that align closely with the capabilities of the ACS37017.
With the launch of the ACS37017, Allegro is positioned to capture a larger share of the high‑accuracy sensor market, reinforcing its strategy to deliver specialized solutions across speed, density, and accuracy for the most demanding power‑electronics applications.
