Typical Applications
ADUM5413ARWZ-RL7 is suitable for 6 applications: Industrial Fieldbus Isolation, Isolated SPI/UART Interface, Power Supply Control, Medical Equipment Isolation, Isolated Sensor Interface, Isolated Gate Driver Power.
Industrial Fieldbus Isolation
The ADUM5413ARWZ-RL7 provides galvanic isolation for industrial fieldbus interfaces such as RS-485, CAN, and Profibus. Its integrated isoPower converter supplies isolated power to the bus transceiver, eliminating the need for a separate isolated DC-DC converter. With a data rate of 150 Mbps and CMTI of 25 kV/Β΅s, it ensures reliable communication in noisy industrial environments. The 2.5 kVrms isolation rating protects control electronics from ground loops and voltage transients. This solution reduces board space and component count, simplifying design and improving reliability.
Recommended
Isolated SPI/UART Interface
The ADUM5413ARWZ-RL7 is ideal for isolating SPI or UART interfaces between microcontrollers and peripheral devices. Its four channels can be configured for bidirectional communication, and the integrated DC-DC converter powers the isolated side. The high data rate of 150 Mbps supports fast SPI clocks, while the low propagation delay of 24 ns minimizes latency. The device operates from 3.0V to 5.5V, making it compatible with both 3.3V and 5V logic. This simplifies the design of isolated sensor interfaces and data acquisition systems.
Recommended
Power Supply Control
In power supply designs, the ADUM5413ARWZ-RL7 provides isolated feedback and control signals between the primary and secondary sides. The integrated isoPower converter can power the secondary-side control circuitry, eliminating the need for an auxiliary winding. The device's high CMTI ensures stable operation in the presence of switching noise. With up to 500 mW of isolated power, it can drive optocouplers, gate drivers, or small microcontrollers. This reduces component count and improves reliability compared to discrete isolation solutions.
Recommended
Medical Equipment Isolation
The ADUM5413ARWZ-RL7 is suitable for medical devices requiring patient isolation, such as ECG monitors, defibrillators, and infusion pumps. Its 2.5 kVrms isolation rating meets safety standards for medical equipment. The integrated DC-DC converter provides isolated power to sensors and analog front-ends, reducing leakage currents. The high data rate and low propagation delay ensure accurate signal transmission for real-time monitoring. The device's small footprint and high reliability make it ideal for portable medical devices.
Recommended
Isolated Sensor Interface
The ADUM5413ARWZ-RL7 can isolate sensor interfaces in industrial and automotive applications. It provides galvanic isolation between sensors and the main controller, preventing ground loops and noise interference. The integrated DC-DC converter powers the sensor side, simplifying wiring. With a data rate of 150 Mbps, it can handle high-speed sensor data such as from encoders or resolvers. The wide operating temperature range of -40Β°C to +125Β°C makes it suitable for harsh environments.
Recommended
Isolated Gate Driver Power
The ADUM5413ARWZ-RL7 can provide isolated power and signal isolation for gate drivers in power electronics. The integrated DC-DC converter supplies the gate driver's floating supply, while the digital channels transmit PWM signals across the isolation barrier. This eliminates the need for separate isolated power supplies, reducing complexity. The high CMTI ensures reliable operation in the presence of fast switching transients. The device is suitable for motor drives, inverters, and switch-mode power supplies.

- Higher data rate (vs ADUM5403ARWZ-RL)
- Lower propagation delay (vs ADUM5403ARWZ-RL)
Design Notes
For the ADUM5413ARWZ-RL7, ensure proper PCB layout with adequate creepage and clearance distances for the 2.5 kVrms isolation rating. Maintain a minimum of 8 mm creepage and clearance between primary and secondary sides. Use a solid ground plane under the device to reduce EMI. Place decoupling capacitors close to VDD1 and VDD2 pins.
The integrated isoPower converter requires careful selection of external components. Use a ferrite bead and capacitors on the input supply to filter noise. The output power is limited to 500 mW; ensure the load does not exceed this. For higher power, consider using an external isolated DC-DC converter.
The ADUM5413ARWZ-RL7 dissipates power internally due to the DC-DC converter. At maximum load, the power dissipation can be significant. Ensure adequate thermal relief on the PCB, such as thermal vias under the device, to keep the junction temperature within limits. The operating temperature range is -40Β°C to +125Β°C.
