ADM3054 5 kV rms Signal Isolated High Speed CAN Transceiver with Bus Protection

Product Details

The ADM3054 is a 5 kV rms signal isolated controller area network (CAN) physical layer transceiver. The ADM3054 complies with the ISO 11898 standard.

The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator and a CAN transceiver into a single package. The logic side of the device is powered with a single 3.3 V or 5 V supply on VDD1 and the bus side uses a single 5 V supply on VDD2 only. Loss of power on the bus side (VDD2) can be detected by an integrated VDD2SENSE signal.

The ADM3054 creates an 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 integrated protection on the bus pins, CANH and CANL against shorts to power/ground in 24 V systems.

The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where the bus might 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.
