Typical Applications
ADM3052BRWZ is suitable for 6 applications: Industrial Fieldbus Networks, Building Automation Systems, Automotive Diagnostics, Medical Equipment, Renewable Energy Systems, Transportation and Rail.
Industrial Fieldbus Networks
The ADM3052BRWZ provides galvanic isolation and robust communication for industrial CAN networks. Its 5 kVrms isolation protects logic-side controllers from ground loops and high common-mode voltages common in factory automation. The integrated linear regulator simplifies power supply design by accepting 24V bus supplies and generating a regulated 5V for the bus side, reducing component count. With 1 Mbps data rate and -40°C to +85°C operation, it suits harsh industrial environments.

The ADM3052BRWZ is used in automotive diagnostic systems for CAN communication between ECUs and test equipment. Its isolation protects diagnostic tools from high common-mode voltages in vehicle electrical systems. The integrated regulator simplifies powering the bus side from the vehicle's 12V or 24V supply. With 1 Mbps data rate and robust transient immunity of 25 kV/µs, it ensures reliable communication in electrically noisy automotive environments. The -40°C to +85°C range covers under-hood and in-cabin temperature extremes.
Recommended
Medical Equipment
The ADM3052BRWZ provides isolated CAN communication in medical devices such as patient monitors and imaging systems. The 5 kVrms isolation ensures patient safety by separating low-voltage control circuits from high-voltage power sections. The integrated regulator reduces board space and simplifies power design, which is critical in compact medical devices. Its low EMI and robust transient immunity help meet medical EMC standards. The wide temperature range and high reliability make it suitable for continuous operation in clinical environments.

- Higher isolation voltage than non-isolated alternatives (vs ADM3051BRWZ)
- Lower cost and lower EMI than ADM3053 (vs ADM3053BRWZ)
Design Notes
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.
