[原创] ADI ADM3055ECAN物理层收发器解决方案

ADI公司的ADM3055E是5kV rms隔离式控制器区域网络(CAN)物理层收发器,采用iCoupler®技术,在SOIC封装内集成了三路隔离器,CAN收发器,和isoPower® DC/DC 转换器,可满足工作速率为 5Mbps及以上的CAN灵活数据(FD)速率要求,并符合ISO 11898-2标准,工作温度−40℃到+105℃,工作电压5V,主要用在CANOpen, DeviceNet和其它CAN总线应用,工业自动化,过程控制和建筑物控制以及交通和基础设备.本文介绍了ADM3055E主要特性,功能框图以及评估板EVAL-ADM3055EEBZ主要特性,电路图,材料清单和PCB设计图.

The ADM3055E is a 5 kV rms isolated controller area network (CAN) physical layer transceiver with an integrated isolated dc-to-dc converter. The ADM3055E meets CAN flexible data (FD) rate requirements for operation to 5 Mbps and higher, and complies with the ISO 11898-2 standard.

The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a CAN transceiver, and Analog Devices isoPower® dc-to-dc converter into a single, small outline integrated circuit (SOIC), surface-mount package. The device is powered by a single 5 V supply realizing a fully isolated solution for CAN and CAN FD applications. Radiated emissions from the high frequency switching of the dc-to-dc convertor are kept below EN 55022 Class B limits by continuous adjustments to the switching frequency.
