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 limi...
