ISO1044 - Isolated CAN FD Transceiver in Small Package

ISO1044 - Isolated CAN FD Transceiver in Small Package

 

TEXAS INSTRUMENTS

 

Description

ISO1044B 장치는 ISO11898-2(2016) 표준 사양을 충족하는 갈바닉 절연 CAN(Controller Area Network) 트랜시버입니다. ISO1044B 장치는 ±58V DC 버스 오류 보호 및 ±12V 공통 모드 전압 범위를 제공합니다. 이 장치는 CAN FD 모드에서 최대 5Mbps의 데이터 속도를 지원하므로 기존 CAN에 비해 훨씬 빠른 페이로드 전송이 가능합니다. 이 장치는 내전압이 3000VRMS이고 작동 전압이 450VRMS인 이산화규소(SiO2) 절연 장벽을 사용합니다. 시스템 수준의 ESD, EFT, 서지 및 방출 규정을 준수할 수 있도록 전자기 호환성이 크게 향상되었습니다. 절연된 전원 공급 장치와 함께 사용되는 이 장치는 고전압으로부터 보호하고 버스의 잡음 전류가 로컬 접지로 유입되는 것을 방지합니다. ISO1044B 장치는 –40°C ~ +125°C의 넓은 주변 온도 범위를 지원합니다. 이 장치는 CAN 트랜시버를 분리하기 위해 광커플러를 사용하는 기존 접근 방식에 비해 솔루션 크기를 크게 줄이는 소형 SOIC-8(D) 패키지로 제공됩니다.

진실한 사랑이란 

하나님을 향한 우리의 사랑이 아니라, 

우리를 향한 하나님의 사랑인 것입니다. 

하나님은 당신의 아들을 보내셔서 우리의 죄를 위해 화목 제물이 되게 하셨습니다.
