MAX3051

+3.3V、1Mbps、低电源电流CAN收发器


点击查看特定型号的库存状况。

说明

MAX3051用于CAN协议控制器和控制局域网(CAN)总线物理连线的接口。MAX3051为总线提供差分传输能力,为CAN控制器提供差分接收能力。MAX3051适用于+3.3V供电、不受汽车工业(ISO 11898)规范故障保护限制的应用。

MAX3051具有四种不同的工作模式:高速、斜率控制、待机与关断模式。高速模式下最高数据速率为1Mbps。斜率控制模式可以控制发送器的摆率,最高数据速率为500kbps,降低了EMI辐射,允许使用非屏蔽的双绞或平行电缆。待机模式下,发送器被关断,接收器被拉高,将MAX3051置为低电流模式。关断模式下,发送器和接收器都被关闭。

MAX3051输入共模范围为-7V至+12V,超出了ISO 11898的-2V至+7V额定范围。这些功能以及可编程的摆率限制功能,使其可理想用于非汽车领域的苛刻环境中。MAX3051采用8引脚SO和SOT23封装,工作在-40°C至+80°C扩展级温度范围内。
