The ADM3054 5 V operation on VDD2 complies with the ISO 11898 standard. V to detect loss of power on V DD2SENSE DD2 The device employs Analog Devices, Inc., iCoupler® technology Complies with ISO 11898 standard to combine a 3-channel isolator and a CAN transceiver into a High speed data rates of up to 1 Mbps single package. The logic side of the device is powered with a Short-circuit protection on CANH and CANL against shorts to single 3.3 V or 5 V supply on V and the bus side uses a single DD1 power/ground in 24 V systems 5 V supply on V only. Loss of power on the bus side (V ) DD2 DD2 Unpowered nodes do not disturb the bus can be detected by an integrated V signal. DD2SENSE Connect 110 or more nodes on the bus Thermal shutdown protection The ADM3054 creates an isolated interface between the CAN High common-mode transient immunity: >25 kV/μs protocol controller and the physical layer bus. It is capable of Safety and regulatory approvals running at data rates of up to 1 Mbps. UL recognition The device has integrated protection on the bus pins, CANH 5000 V rms for 1 minute per UL 1577 and CANL against shorts to power/ground in 24 V systems. VDE Certificates of Conformity The device has current-limiting and thermal shutdown features DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 to protect against output short circuits and situations where the V = 846 V peak IORM bus might be shorted to ground or power terminals.

Data Sheet ADM3054 THEORY OF OPERATION CAN TRANSCEIVER OPERATION TRUTH TABLES A CAN bus has two states: dominant and recessive. A dominant The truth tables in this section use the abbreviations listed state is present on the bus when the differential voltage between in Table 8. CANH and CANL is greater than 0.9 V. A recessive state is present Table 8. Truth Table Abbreviations on the bus when the differential voltage between CANH and Letter Description CANL is less than 0.5 V. During a dominant bus state, the CANH H High level pin is high and the CANL pin is low. During a recessive bus L Low level state, both the CANH and CANL pins are in the high imped- I Indeterminate ance state. X Don’t care The driver drives CANH high and CANL low (dominant state) Z High impedance (off) when a logic low is present on TxD. If a logic high is present on NC Disconnected TxD, the driver outputs are placed in a high impedance state (recessive state). The driver output states are presented in Table 9. Table 9.

ADM3054 Data Sheet ELECTRICAL ISOLATION iCoupler Technology In the ADM3054, electrical isolation is implemented on the The digital signals transmit across the isolation barrier using logic side of the interface. Therefore, the device has two main iCoupler technology. This technique uses chip scale transformer sections: a digital isolation section and a transceiver section windings to couple the digital signals magnetically from one (see Figure 29). The driver input signal, which is applied to the side of the barrier to the other. Digital inputs are encoded into TxD pin and referenced to the logic ground (GND), is coupled waveforms that are capable of exciting the primary transformer 1 across an isolation barrier to appear at the transceiver section winding. At the secondary winding, the induced waveforms are referenced to the isolated ground (GND). Similarly, the receiver decoded into the binary value that was originally transmitted. 2 input, which is referenced to the isolated ground in the tran- Positive and negative logic transitions at the input cause narrow sceiver section, is coupled across the isolation barrier to appear (~1 ns) pulses to be sent to the decoder via the transformer. The at the RxD pin referenced to the logic ground. decoder is bistable and is, therefore, set or reset by the pulses, indicating input logic transitions. In the absence of logic transitions at the input for more than ~1 μs, a periodic set of refresh pulses, indicative of the correct input state, are sent to ensure dc correct- ness at the output. If the decoder receives no internal pulses for more than about 5 μs, the input side is assumed to be unpowered or nonfunctional, in which case the output is forced to a default state (see Table 9).

The following analysis defines the conditions For example, at a magnetic field frequency of 1 MHz, the under which this may occur. The 3 V operating condition of the maximum allowable magnetic field of 0.2 kgauss induces a ADM3054 is examined because it represents the most susceptible voltage of 0.25 V at the receiving coil. This is approximately mode of operation. 50% of the sensing threshold and does not cause a faulty output transition. Similarly, if such an event occurs during a transmitted The pulses at the transformer output have an amplitude greater pulse and is the worst-case polarity, it reduces the received pulse than 1 V. The decoder has a sensing threshold of about 0.5 V, from >1.0 V to 0.75 V, still well above the 0.5 V sensing threshold thus establishing a 0.5 V margin in which induced voltages can of the decoder. be tolerated.
