ADM3052BRWZ - Isolated CAN Transceiver with Regulator | Analog Devices
MPN： ADM3052BRWZ ✓ 啟用中ADM3052BRWZ 概覽
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.

主要差異化特點
- Integrated linear regulator simplifies power design (對比ISO1050DW)
- Higher isolation voltage than non-isolated alternatives (對比ADM3051BRWZ)
- Lower cost and lower EMI than ADM3053 (對比ADM3053BRWZ)
設計說明
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.
