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.
The ADM3055E provides complete isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for 5 kV withstand voltage, 565 VPEAK working voltage, 10 kV surge test, and 8.3 mm creepage and clearance ensure that the ADM3055E meets application isolation requirements.
Low propagation delays through the isolation support longer bus cables. Slope control mode is available for standard CAN at low data rates. Standby mode minimizes power consumption when the bus is idle or if the node goes offline. Silent mode allows the TXD input to be ignored for listen only.
Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The device is fully specified over an industrial temperature range of −40℃ to +105℃.

Evaluating the ADM3055E 5 kV rms, Signal and Power Isolated, CAN Transceiver for CAN FD
The EVAL-ADM3055EEBZ allows the user to evaluate the ADM3055E isolated signal and power transceiver for controller area network (CAN) or CAN with flexible data rate (CAN FD) networks. The EVAL-ADM3055EEBZ allows all of the input and output functions to work without the need for external components. Based on the Analog Devices, Inc., iCoupler® technology, the ADM3055E integrates logic side on-off keying (OOK) signal isolation channels and an Analog Devices isoPower® dc-to-dc converter to provide regulated, isolated power that is well below CISPR22/EN55022 Class B limits when transmitting on a 2-layer printed circuit board (PCB) with ferrites.The EVAL-ADM3055EEBZ comes populated with an ADM3055E. Full specifications of the ADM3055E can be found in the ADM3055E data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the EVAL-ADM3055EEBZ.
