ADUM2250ARWZ-RL

Overview

The ADUM2250ARWZ-RL is a hot-swappable digital isolator from Analog Devices, designed for I2C interfaces. It features two bidirectional communication channels with a data rate of 1 Mb/s and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V, drawing typical currents of 2.7 mA and 2.8 mA on its respective sides. It exhibits a propagation delay of 162 ns and a common mode transient immunity of 25 kV/µs. The component is housed in a 16-SOIC package and supports operation temperatures from -40°C to +105°C.

Feature Summary

• Hot-swappable capability allows connection or disconnection while the system is powered without damage.
• Nonlatching bidirectional communication channels ensure reliable data transfer for I2C protocols.
• High common mode transient immunity protects against noise in electrically noisy environments.

Applications

• I2C bus isolation in industrial automation systems
• Isolating microcontrollers from peripheral devices in medical equipment
• Protecting control circuits in automotive electronic control units

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the ARWZ designation corresponds to the SOIC-16 wide body package. Ensure the manufacturer is Analog Devices Inc. Check RoHS compliance status through official documentation before integration.

Selection Notes

Select this component when high isolation voltage and hot-swap functionality are required for I2C buses. Consider the 16-SOIC package size for board space constraints. Evaluate the 5000 Vrms rating against system safety requirements. Compare power consumption figures if battery life is critical.

Part Context

This part belongs to the ADuM2250 series of digital isolators. It utilizes magnetic coupling technology for signal transmission across the isolation barrier. The series is designed to replace traditional optocouplers in applications requiring higher reliability and lower power consumption.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADuM2250 family. Verify that alternative parts support the same 1 Mb/s data rate and 5000 Vrms isolation level. Ensure thermal performance matches the original specifications.
