Latest addition to Allegro’s transmission speed sensor family improves system design efficiency for optimal fuel economy
Allegro MicroSystems, a global leader in power and sensing solutions for motion control and energy efficient systems, has announced the release of theATS19580, the industry’s first fully-integrated, back-biased GMR transmission speed and direction sensor. Achieving the highest level of in-system performance for this application, the ATS19580 reduces system size, complexity and cost—resulting in improved fuel economy.
Combining GMR technology with Allegro’s leading transmission algorithms and packaging, the ATS19580 offers the highest performance transmission sensor to date, including:
- The widest dynamic range of operating air gap (50% larger)
- Industry-leading vibration immunity
- EMC protection
- Robust to common-mode stray fields
“By monolithically integrating our proprietary GMR technology with leading digital processing we’ve set a new standard for transmission speed sensing, achieving the highest level of in-system performance ever,” explains Peter Wells, Business Unit Director at Allegro. “The ATS19580’s ability to reach formerly unachievable airgaps with the best vibration performance on the market simplifies the customers’ Speed Sensor integration and allows them to design safe, fuel efficient systems.”
Helping to meet today’s fuel efficiency standards
As the automotive industry continues to push for more efficient fuel consumption and carbon dioxide emissions reductions, Allegro is leading the way in offering innovative and energy efficient solutions like the ATS19580.
The device’s GMR technology improves performance and extends air gap capability over existing Hall solutions, which allows for more installation flexibility. Key in the automotive industry, this flexibility reduces system size, which in turn, reduces costs for automakers and improves fuel economy.
Fully-integrated solution for performance and ease of use
Monolithic integration not only allows for the highest levels of in-system performance—like vibration immunity, dynamic air gap capability, and accurate direction detection—it also allows for ease of design-in with IC, magnet, and protection components in a single, overmolded package. Allegro’s advanced digital algorithms in the ATS19580 also allow for flexible design-in and system compensation.

TheATS19580complements Allegro’s recently releasedATS19420andATS19520完全集成，霍尔效应传输速度传感器，以及Allegro的前偏置霍尔效应和GMR系列产品的磁性目标传感器g. These ICs, combined with the soon-to-be released ATS19480, a GMR transmission speed only sensor, provides customers the broadest portfolio of transmission speed sensors available on the market. All of these devices are built upon Allegro’s 20 years of application-specific experience and technological advancement—and in direct response to the needs of today’s automotive manufacturers.
