MPN: ADUM5402ARWZ ✓ فعالADUM5402ARWZ جائزہ
Digital isolators are components that transfer digital signals across an isolation barrier without a direct electrical connection, using capacitive or magnetic coupling. They are essential in applications requiring galvanic isolation for safety, noise immunity, or ground potential differences. The ADUM5402 belongs to the family of isolated interface ICs, which combine signal isolation with power transfer, enabling complete isolation of a subsystem without separate isolated power supplies.
Key features of the ADUM5402ARWZ include four independent isolation channels, an integrated DC-to-DC converter delivering up to 500 mW of regulated output power, and a wide supply voltage range of 3.0V to 5.5V on the primary side. The device uses Analog Devices' iCoupler technology, which provides superior performance compared to optocouplers, including higher data rates, lower power consumption, and better reliability.
The ADUM5402ARWZ is designed for applications requiring isolated power and data transfer, such as industrial field buses, isolated SPI/UART interfaces, and isolated sensor data acquisition. Its integrated DC-to-DC converter eliminates the need for a separate isolated power supply, simplifying board design and reducing component count. The device also features a soft-start function to limit inrush current during power-up.
Typical applications include isolated RS-485/RS-232 interfaces, isolated power supplies for data converters, and isolated communication in motor drives and power inverters. The ADUM5402ARWZ is also suitable for medical equipment requiring patient isolation, where its 2.5 kVrms isolation rating meets safety standards.
When designing with the ADUM5402ARWZ, it is important to ensure proper PCB layout to maintain isolation spacing and to place decoupling capacitors close to the power pins. The integrated DC-to-DC converter requires careful attention to the output capacitor selection to ensure stable operation.

ڈیزائن نوٹس
For the ADUM5402ARWZ, maintain proper creepage and clearance distances on the PCB to meet the 2500 Vrms isolation rating. Use a minimum of 8mm creepage and 8mm clearance between primary and secondary sides. Place the device with a slot or cutout under the package to enhance isolation. Ensure the PCB material has adequate insulation properties.
The integrated DC-to-DC converter requires a low-ESR output capacitor (typically 1µF to 10µF) on the VISO pin to ensure stable operation. The input supply should be decoupled with a 0.1µF capacitor close to the VDD1 pin. The total output power is limited to 500 mW; ensure the load does not exceed this to avoid thermal shutdown.
Keep the isolation barrier clear of any copper traces or components. The high CMTI of 25 kV/µs requires careful layout to avoid coupling of transients. Use a solid ground plane on each side of the isolation barrier, but do not connect them together. Place the device close to the board edge to facilitate isolation spacing.
