(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 transceiver, and
Analog Devices isoPower® dc-to-dc converter into a single
SOIC surface mount package. An on-chip oscillator 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 details on board layout considerations
