GENERAL DESCRIPTION

The ADM3052 is an isolated controller area network (CAN)

physical layer transceiver with a V+ integrated linear regulator. The ADM3052 complies with the ISO 11898 standard. The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a CAN transceiver, and a linear

regulator into a single package. The power is isolated between a single 3.3 V or 5 V supply on VDD1, the logic side, and a single

24 V supply provided on V+, the bus side.

The ADM3052 creates an isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates up to 1 Mbps. The device has integrated miswire protection on the bus pins, V+, V−, CANH, and CANL. The device has current-limiting and thermal shutdown features

to protect against output short circuits and situations where the

bus may be shorted to ground or power terminals. The device is fully specified over the industrial temperature range and is

available in a 16-lead, wide-body SOIC package.
