GENERAL DESCRIPTION:

The ADM3053 is an isolated controller area network (CAN)physical layer transceiver with an integrated isolated dc-to-dcconverter. The ADM3053 complies with the ISO 11898 standard.The device employs Analog Devices, Inc., iCoupler® technologyto combine a 2-channel isolator, a CAN transceiver, and AnalogDevices isoPower® dc-to-dc converter into a single SOIC surfacemount package. An on-chip oscillator outputs a pair of squarewaveforms that drive an internal transformer to provide isolatedpower. The device is powered by a single 5 V supply realizing afully isolated CAN solution.The ADM3053 creates a fully isolated interface between theCAN protocol controller and the physical layer bus. It is capableof running at data rates of up to 1 Mbps.The device has current limiting and thermal shutdown featuresto protect against output short circuits. The part is fully specifiedover the industrial temperature range and is available in a20-lead, wide-body SOIC package.The ADM3053 contains isoPower technology that uses highfrequency switching elements to transfer power through thetransformer. Special care must be taken during printed circuitboard (PCB) layout to meet emissions standards. Refer to theAN-0971 Application Note, Recommendations for Control ofRadiated Emissions with isoPower Devices, for details on boardlayout considerations.
