ISO7762FQDWQ1

Overview

The ISO7762FQDWQ1 is a Texas Instruments automotive-grade digital isolator featuring six channels with three inputs and three outputs. It utilizes capacitive coupling technology to provide reinforced isolation with a rated insulation voltage of 5000 Vrms. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. It is housed in a 16-pin SOIC package and certified to AEC-Q100 standards for temperatures ranging from -40°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility performance suitable for demanding automotive environments.
• Offers high-speed signal transmission capabilities with low propagation delay characteristics.
• Delivers reinforced galvanic isolation between input and output domains using capacitive sensing technology.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Inverter gate drive circuits in electric vehicle powertrains
• Battery management systems needing isolated sensor feedback

Procurement Notes

Verify the specific suffix 'FQDWQ1' against official Texas Instruments documentation to confirm the exact pinout, temperature grade, and packaging configuration. Ensure that the component meets the required AEC-Q100 qualification levels for your specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when a six-channel isolator is required for high-speed automotive applications. Consider the bidirectional or unidirectional channel configurations available within the ISO776x family to match system topology needs. Evaluate the 5000 Vrms isolation rating against system safety requirements.

Part Context

This part belongs to the ISO776x-Q1 series of high-speed, robust EMC digital isolators designed specifically for automotive use. It complements other members like the ISO7742 and ISO7763 by offering a six-channel solution in a standard SOIC-16 footprint, facilitating design reuse across different isolation channel counts.

Replacement Considerations

Consult the Texas Instruments ISO776x family cross-reference for direct pin-compatible alternatives such as the ISO7762FQDWRQ1. Verify functional equivalence regarding channel count and isolation ratings before substitution.
