A position sensor used to monitor rotational speed is a speed sensor. They can be found in a variety of commercial and racing vehicles.
A speed sensor, like many other devices, is essential to onboard systems. By supplying a voltage measurement matching the magnetic rotating speed, they function.
They are used in situations where it is necessary to assess speed without making contact in challenging-to-access locations.
Devices’ internal spinning speeds are measured using speed sensors. Automotive, aeronautical, off-road & construction, railroad, and military vehicles are just a few of the many types of vehicles that need speed sensors.
The Global Motor Speed Sensor ICs market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A set of contactless, Hall-effect-based magnetic sensor ICs for high-speed motor position sensing in safety-critical automotive applications are offered by Allegro MicroSystems as the A1331 and A1334.
With a system-on-chip architecture that offers quick output refresh rates and little signal route delay, Allegro’s dual-die A1331, and A1334 angle sensor ICs are based on vertical Hall-effect technology.
Two separately sawn, electrically isolated silicon ICs are contained in the TSSOP-24 packaging that each device is provided in.
Particularly in ASIL-compliant automotive systems, their dual-die functionality makes them acceptable for use in safety-critical applications that need the use of redundant sensor ICs.
For applications that do not require redundancy, the A1334 is also available in the TSSOP-14 package in a single-die configuration.
