Achieving the highest level of in-system performance for this application, the ATS19580 reduces system size, complexity and cost - resulting in improved fuel economy.
By combining GMR technology with Allegro’s transmission algorithms and packaging, the ATS19580 is able to offer much improved performance offering the widest dynamic range of operating air gap (50% larger), vibration immunity, EMC protection and robust to common-mode stray fields.
The device’s GMR technology improves performance and extends air gap capability over existing Hall solutions, which allows for more installation flexibility reducing system size, which in turn, reduces costs for automakers and improves fuel economy.
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, over-molded package. Allegro’s advanced digital algorithms in the ATS19580 also allow for flexible design-in and system compensation.
This back-biased IC is provided in a 3-pin SIP package (suffix SN) that is lead (Pb) free, with tin leadframe plating.
The ATS19580 complements Allegro’s recently released ATS19420 and ATS19520 fully-integrated, Hall-effect transmission speed sensors, as well as Allegro’s family of front-biased Hall-effect and GMR products for magnetic target sensing. These ICs, combined with the soon-to-be released ATS19480, a GMR transmission speed only sensor, will provide customers with a broad portfolio of transmission speed sensors.
