说明

ISO1044B 器件是一款符合 ISO11898-2 (2016) 标准规格的电隔离控制器局域网 (CAN) 收发器。ISO1044B 器件提供 ±58V 直流总线故障保护电压和 ±12V 共模电压范围。该器件在 CAN FD 模式下最高支持 5Mbps 数据速率,与经典 CAN 相比可实现更为快速的载荷传输。该器件采用二氧化硅 (SiO2) 绝缘隔栅,可承受 3000VRMS 的电压和 450VRMS 的工作电压。电磁兼容性得到了显著增强,可实现系统级 ESD、EFT 和浪涌并符合辐射标准。与隔离式电源一起使用,此器件可抵御高电压冲击,并防止总线的噪声电流进入本地接地。ISO1044B 器件支持 –40°C 至 +125°C 的宽环境温度范围。该器件可采用小型 SOIC-8 (D) 封装,与使用光耦合器隔离 CAN 收发器的传统方法相比,能显著降低解决方案尺寸。
