ADUM5413ARWZ-RL7 - Quad-Channel Digital Isolator with isoPower | Analog Devices
MPN： ADUM5413ARWZ-RL7 ✓ 啟用中ADUM5413ARWZ-RL7 概覽
Digital isolators are components that transmit digital signals across an isolation barrier, providing galvanic isolation to protect sensitive circuitry from high voltages, noise, and ground loops. They are essential in industrial, medical, and communication systems where safety and signal integrity are critical. The ADUM5413 integrates the isolation barrier with a DC-to-DC converter, making it a complete isolated power and data solution.
Key features include four isolated channels (two forward, two reverse), a data rate of up to 150 Mbps, and a propagation delay of 24 ns. The integrated DC-to-DC converter provides up to 500 mW of output power with an efficiency of up to 33%. The device operates from a 3.0V to 5.5V supply and offers a wide operating temperature range of -40°C to +125°C.
The ADUM5413 uses Analog Devices' iCoupler technology, which employs chip-scale transformers instead of optocouplers, offering higher reliability, faster data rates, and lower power consumption. The integrated isoPower converter uses a push-pull architecture to generate isolated power, reducing external component count and board space.
Typical applications include industrial fieldbus isolation, isolated SPI/UART interfaces, power supply control, and medical equipment isolation. The device is ideal for systems requiring both data and power isolation in a compact form factor.
When designing with the ADUM5413, ensure proper PCB layout with adequate creepage and clearance distances for the required isolation rating. The integrated converter requires careful selection of external components, such as the transformer and rectifier diodes, to achieve optimal performance.

設計說明
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 -40°C to +125°C.
