Signal and Power Isolated CAN Transceiver (ADM3053)

The ADM3053 is an isolated controller area network (CAN) physical layer transceiver with an integrated isolated
dc-to-dc converter. The ADM3053 complies with the ISO 11898 standard.
The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiv-
er, and Analog Devices isoPower® dc-to-dc converter into a single SOIC surface mount package. An on-chip oscil-
lator outputs a pair of square waveforms that drive an internal transformer to provide isolated power. The device is
powered by a single 5 V supply realizing a fully isolated CAN solution.
The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It
is capable of running at data rates of up to 1 Mbps.
The device has current limiting and thermal shutdown features to protect against output short circuits. The part is
fully specified over the industrial temperature range and is available in a 20-lead, wide-body SOIC package.
The ADM3053 contains isoPower technology that uses high frequency switching elements to transfer power
through the transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions
standards. Refer to the AN-0971 Application Note, Control of Radiated Emissions with isoPower Devices, for de-
tails on board layout considerations.
