GENERAL DESCRIPTION

The EVA L-ADM3052EBZ allows quick and easy evaluation of the

ADM3052 isolated CAN transceiver. The evaluation board allows

all the input and output functions of the ADM3052 to be

exercised without the need for external components.

The ADM3052 is an isolated CAN, physical layer transceiver

with a V

integrated linear regulator. The ADM3052 complies

with the ISO 11898 standard.

The device uses Analog Devices, Inc., iCoupler® technology to

combine a 3-channel isolator, a CAN transceiver, and a linear

regulator into a single, 16-lead, wide body SOIC package. The

power is isolated between a single 3.3 V or 5 V supply on V

DD1

, the

logic side, and a single 24 V supply provided on V

, the bus side.

The linear regulator takes the V

bus power and regulates it

down to 5 V. The linear regulator uses two regulation loops

to share the power dissipation between the internal die and an

external resistor (R1), which reduces the internal heat dissipation

in the package. This 300 Ω external resistor should be capable

of dissipating 750 mW of power and have a tolerance of 1%.

Full details on the ADM3052 are provided in the ADM3052

data sheet available from Analog Devices, Inc., which should be

consulted in conjunction with this evaluation board user guide.

EVALUATION BOARD CONFIGURATION

SETTING UP THE EVALUATION BOARD

The E VA L-ADM3052EBZ allows the ADM3052 isolated CAN

transceiver to be quickly and easily evaluated. The evaluation

board allows all of the input and output functions to be exercised

without the need for external components.

On the E VA L -ADM3052EBZ, 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.

R1, the 300 Ω external resistor, is used by the built-in linear

regulator to share the power dissipation between R1 and the

internal die to reduce the internal heat dissipation in the package.

The bus voltage sense pin (V+SENSE), detects when V+ is

connected on the bus side. A low on V+SENSE indicates that

power is available on the bus side, and a high on V+SENSE

indicates that power is absent from the bus side.

VDD1 is the power supply of the logic side. A 22 µF decoupling

capacitor, C5, is fitted between VDD1 and GND1. A capacitor

of 1 µF is fitted on the C

INT

pin. A 100 nF capacitor, C6, is fitted

between V+ and V−, and a 10 µF capacitor, C7, is fitted between

V+R and V−.

An example operation of the EVAL-ADM3052EBZ is shown in

Figure 3. Connect a signal generator on TXD and set up a 500 kHz

square wave clock with output swing between 0 V and 5 V. C on n e c t

the scope probes to the CANH and CANL test points. A plot of

the oscilloscope for TXD, CANH, and CANL is shown in Figure 2.

Channel 1 shows the TXD signal, and Channel 2 and Channel 3

show the CANH and CANL signals, respectively.
