Overview
The SI88441ED-ISR is a Skyworks Solutions digital isolator featuring four channels with an integrated DC-DC converter. It provides 5000 Vrms isolation via capacitive coupling and supports data rates up to 100 Mb/s. The device operates on a supply voltage of 3 V to 5.5 V, with a maximum propagation delay of 18 ns. It includes three forward and one reverse channel, housed in a 20-SOIC package. The component functions within a temperature range of -40°C to +125°C and offers a common-mode transient immunity of 40 kV/µs.
Feature Summary
- Integrates a high-voltage DC-DC converter for isolated power generation
- Provides robust capacitive coupling insulation rated at 5000 Vrms
- Supports general-purpose bidirectional signal transmission with shutdown capability
Applications
- Industrial automation control systems
- Medical equipment requiring galvanic isolation
- Power electronics monitoring interfaces
Procurement Notes
Verify the NRND status before integration, as this component is not recommended for new designs. Confirm that the specific ISR suffix matches the required reel packaging format. Ensure compatibility with the 20-SOIC footprint during PCB layout. Validate that the integrated DC-DC converter meets the target system's power budget requirements.
Selection Notes
Choose this part when high isolation voltage and integrated power conversion are necessary. Compare against non-isolated alternatives if power constraints are critical. Consider the 100 Mb/s speed limit for high-frequency applications. Evaluate thermal performance within the specified operating temperature range.
Part Context
This component belongs to the Si88441 series of high-speed digital isolators. It distinguishes itself by embedding a DC-DC converter, eliminating the need for external isolated power supplies. The series targets applications demanding reliable signal integrity across high-voltage barriers.
Replacement Considerations
Check for direct substitutes within the Si8844x family. Verify pinout compatibility for SOIC-20 packages. Ensure equivalent isolation ratings and data rate specifications.
