ADM3052BRWZ Présentation
An isolated CAN transceiver is a component that provides galvanic isolation between the CAN protocol controller and the physical bus, protecting the logic side from high common-mode voltages, ground loops, and electrical noise. It integrates a digital isolator, a CAN transceiver, and often a DC-DC converter or regulator to power the isolated side. In the hierarchy of CAN interface components, it sits above a standard transceiver by adding isolation, which is critical in industrial, automotive, and building automation systems where long bus lengths and differing ground potentials are common.
Key features include a 5 kVrms isolation rating, a bus-side linear regulator with 5V output, and compliance with ISO 11898-2. The device offers a common-mode voltage range of -12V to +12V and a common-mode transient immunity of 25 kV/µs, ensuring robust operation in noisy environments. It also features thermal shutdown protection and a logic-side supply range of 3.0V to 5.5V, making it versatile for various controller interfaces.
Technically, the ADM3052 integrates a 3-channel iCoupler digital isolator for the TXD, RXD, and a control signal, eliminating the need for a separate isolation barrier. The integrated linear regulator simplifies power supply design by generating the isolated 5V bus supply from a higher input voltage, reducing component count and board space. The device is specified for the industrial temperature range of -40°C to +85°C and is available in a 16-lead SOIC-W package.
Typical applications include industrial fieldbus networks, building automation systems, automotive diagnostics, and any CAN bus requiring galvanic isolation. The integrated regulator is particularly useful in systems where a 24V supply is available, as it can directly power the bus side without an external DC-DC converter.
When designing with the ADM3052, ensure proper PCB layout with adequate creepage and clearance for the isolation barrier, and place decoupling capacitors close to the VCC and V+ pins. The bus-side regulator requires an output capacitor for stability, and the input voltage must not exceed the absolute maximum rating of 27V.

Notes de conception
For the ADM3052BRWZ, maintain proper creepage and clearance distances under the SOIC-W package to achieve the 5 kVrms isolation rating. Use a PCB with at least 8 mm creepage between the logic and bus sides. Place a 100 nF decoupling capacitor close to VCC and a 10 µF capacitor on VOUT for regulator stability. Ensure the ground planes are separated under the isolation barrier.
The integrated linear regulator dissipates power as (V+ - VOUT) * IOUT. For example, with V+ = 24V and IOUT = 100 mA, dissipation is 1.9W, which may require thermal relief. Ensure the SOIC-W package has adequate copper area for heat sinking. If higher efficiency is needed, consider the ADM3053 with a DC-DC converter.
Do not exceed the absolute maximum input voltage of 27V on the V+ pin. The bus-side regulator output VOUT must be bypassed with a capacitor (e.g., 10 µF) to prevent oscillation. Also, ensure the logic supply VCC is within 3.0V to 5.5V; operating outside this range can cause communication errors. Refer to the datasheet for the recommended application circuit.
