ISO7310FCQDQ1

Overview

The ISO7310FCQDQ1 is an automotive-grade, low-power, single-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a data rate of 25 Mb/s and a propagation delay of 36 ns. The device operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating current of 3.8 mA. It provides 3000 Vrms isolation voltage and supports a common-mode transient immunity (CMTI) of 25 kV/µs. Packaged in an 8-SOIC format, it functions reliably across a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• Robust electromagnetic compatibility performance with high common-mode transient immunity
• Low power consumption design suitable for energy-efficient applications

Applications

• Automotive engine control units
• Body electronics systems
• Industrial communication interfaces requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'FC' indicates the correct package variant and internal configuration. Confirm that the AEC-Q100 grade meets your project's reliability requirements. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check for moisture sensitivity level compliance during storage and handling procedures.

Selection Notes

Select this component when a single-channel isolator with automotive certification is required. Consider the 25 Mb/s data rate sufficient for your signal speed needs. Evaluate the 3000 Vrms isolation barrier against system safety standards. Compare power consumption against other channels if multiple isolators are needed on the same board.

Part Context

This part belongs to the ISO7310-Q1 family of digital isolators designed for robust EMC performance. It complements other single-channel variants like the ISO7310CQDQ1 by offering specific feature sets tailored for automotive and industrial use cases requiring high reliability and low power operation.

Replacement Considerations

The ISO7310CQDQ1 is a related single-channel variant within the same family. Verify functional equivalence regarding channel count and isolation voltage before substitution.
