ADM3052 Isolated CAN Transceiver with Integrated High Voltage, Bus-Side, Linear Regulator

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 part is fully specified over the industrial temperature range and is available in a 16-lead, wide-body SOIC package.
