ISO7763QDBQRQ1

Overview

The ISO7763QDBQRQ1 is a six-channel digital isolator from the ISO776x-Q1 series, designed for automotive applications. It features three forward and three reverse channels with unidirectional signal flow. The device utilizes capacitive coupling technology to provide electrical isolation. It operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a data rate of 100 Mb/s, an insulation voltage of 3000 Vrms, and a minimum common-mode transient immunity (CMTI) of 85 kV/µs. The propagation delay is typically 11 ns, with rise and fall times under 4 ns. It is housed in a 16-SSOP package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• High-speed data transmission capability supporting up to 100 Mb/s per channel.
• Enhanced electromagnetic compatibility (EMC) robustness for reliable operation in noisy systems.
• Six-channel configuration providing independent isolation paths for complex interface requirements.

Applications

• Automotive gateway systems requiring high-speed data isolation between domains.
• In-vehicle networks such as CAN and LIN interfaces needing robust signal integrity.
• Battery management systems (BMS) where galvanic isolation protects sensitive control electronics.
• Infotainment and display interfaces demanding high bandwidth and low latency.

Procurement Notes

Verify the specific suffix 'DBQRQ1' to confirm the SSOP-16 package and 3000 Vrms isolation rating, as other suffixes may indicate different packages or voltage ratings. Ensure the component meets the required AEC-Q100 grade for your specific automotive application. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Confirm that the 100 Mb/s data rate aligns with your system's timing constraints.

Selection Notes

Select this component when six isolated channels are required in a single package to save board space. It is suitable for designs needing high CMTI to withstand fast-switching noise in power electronics. Consider the 16-SSOP footprint for compatibility with existing layouts. Compare against lower-speed alternatives if 100 Mb/s is excessive, or higher-voltage variants if insulation requirements exceed 3000 Vrms.

Part Context

This part belongs to the ISO776x-Q1 family of high-performance digital isolators. These devices are engineered to replace traditional magnetic couplers in automotive and industrial applications. The family offers various channel configurations and isolation voltages. The ISO7763 variant specifically provides a 3/3 channel split, balancing input and output isolation needs.

Replacement Considerations

Check for ISO7763QDWRQ1 for the same functionality in a wider SOIC-16 package. Verify ISO7760QDBQRQ1 if only unidirectional signals are needed, noting its lower 1 Mb/s speed. Ensure any substitute maintains the AEC-Q100 qualification and compatible pinout for direct replacement.
