Publication number: 20230400477Abstract: Electronic circuits and methods sense an electromagnetic property of a target, and transmit data packets that encode the property along with diagnostic messages while avoiding data loss due to truncation at high sensing speeds. Data address bits may be used to split messages across multiple data packets. Data bits may be combined into a unified header that takes less time to transmit than in prior communication protocols. The transmission duration of each data bit may be lowered, thereby increasing throughput. The receiving system may synchronize its own operation against these shortened data bits, increasing its speed. Error packets may be sent between data packets, thereby reducing time to respond to faults in safety-critical systems. And additional current levels may be used to increase the data information rate.Type: ApplicationFiled: May 18, 2022Publication date: December 14, 2023Applicant: Allegro MicroSystems, LLCInventors: Andreas P.
