Overview

TLE5012B는 자기장의 방향을 감지하는 360° 각도 센서입니다. 이는 모놀리식 통합 거대 자기 저항(iGMR) 요소로 사인 및 코사인 각도 구성 요소를 측정하여 달성됩니다. 이러한 원시 신호(사인 및 코사인)는 자기장(자석)의 각도 방향을 계산하기 위해 내부적으로 디지털 처리됩니다. TLE5012B는 사전 교정된 센서입니다. 교정 매개변수는 레이저 퓨즈에 저장됩니다. 시동 시 퓨즈 값은 플립플롭에 기록되며, 이 값은 애플리케이션별 매개변수에 의해 변경될 수 있습니다. 선택적인 내부 자동 보정 알고리즘을 활성화하면 넓은 온도 범위와 긴 수명에 걸쳐 각도 측정의 정밀도가 더욱 향상될 수 있습니다. 데이터 통신은 SPI와 호환되는 양방향 SSC(동기식 직렬 통신)를 통해 수행됩니다. 센서 구성은 SSC 인터페이스에서 액세스할 수 있는 레지스터에 저장됩니다. 또한 TLE5012B에서는 펄스 폭 변조(PWM) 프로토콜, 짧은 PWM 코드(SPC) 프로토콜, 홀 스위치 모드(HSM) 및 증분 인터페이스(IIF) 등 4개의 다른 인터페이스를 사용할 수 있습니다. 이러한 인터페이스는 SSC와 병렬로 사용하거나 단독으로 사용할 수 있습니다. 다양한 인터페이스 설정으로 사전 구성된 센서 파생 제품을 사용할 수 있습니다.
안정적인 작동을 보장하기 위해 온라인 진단 기능이 제공됩니다.
