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)
- 我ndustry-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.
该器件的GMR技术可提高性能，并在现有的霍尔解决方案方面延长空气隙能力，这允许更多的安装灵活性。钥匙在汽车行业中，这种灵活性降低了系统尺寸，反过来又降低了汽车制造商的成本并提高了燃油经济性。
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.
该后偏置IC设置在3针SIP封装（后缀Sn）中，其具有铅（Pb），具有锡引线框架电镀。
TheATS19580补充Allegro最近发布的ATS19420andATS19520完全集成，霍尔效应传输速度传感器，以及Allegro的前偏见霍尔效应和GMR产品的磁性目标Sensing. 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.
