Overview
The ISOW7741FQDFMRQ1 is an automotive-grade quad-channel digital isolator featuring an integrated DC-DC converter. It provides galvanic isolation with a rated insulation voltage of 5000 Vrms and supports data rates up to 100 Mb/s. The device offers high common-mode transient immunity of 85 kV/µs and operates within a temperature range of -40°C to +125°C. Packaged in a 20-pin SOIC (DFM) format, it ensures low emissions and low ripple performance for robust signal transmission.
Feature Summary
- Integrated DC-DC converter enables single-supply operation without external isolated power sources
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Low electromagnetic interference design minimizes system noise
- High common-mode transient immunity ensures signal integrity in noisy environments
Applications
- Automotive battery management systems
- Inverter control circuits
- Motor drive interfaces
- On-board charging systems
Procurement Notes
Verify the specific suffix FQDFMRQ1 to confirm the tape-and-reel packaging quantity and automotive grade designation. Ensure compatibility with the 20-pin SOIC footprint during PCB layout. Confirm that the integrated DC-DC converter requirements align with the target application's power budget and thermal constraints before finalizing procurement.
Selection Notes
Select this component when integrated isolated power is required to simplify board design and reduce component count. It is suitable for applications demanding high reliability and strict electromagnetic compatibility standards. Consider the 20-pin package size and thermal dissipation capabilities relative to available board space and cooling methods.
Part Context
This part belongs to the ISOW774x-Q1 family of quad-channel digital isolators with integrated converters. It complements standard isolators by providing both signal isolation and isolated power generation in a single package, reducing the complexity of designing isolated power domains in automotive and industrial systems.
Replacement Considerations
Direct replacements must include an integrated DC-DC converter and match the 20-pin SOIC package. Verify that alternative parts meet the same AEC-Q100 Grade 1 qualification and offer comparable insulation voltage and CMTI specifications.
