[原创] ADI ADM3055E 5kVrms隔离CAN物理层收发器解决方案

ADI公司的ADM3055E是集成了隔离DC/DC转换器的5kVrms隔离的CAN物理层收发器,满足CAN灵活数据(FD)速率要求,可以工作高达5Mbps或更高,并和ISO 11898-2标准兼容.器件采用ADI的iCoupler®技术,把三路隔离器,CAN收发器和ADI isoPower® DC/DC转换器集成在SOIC表面安装封装中,工作电压5V,工作温度−40℃到 +105℃,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运输和基础设备.本文介绍了ADM3055E主要特性和功能框图,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.
