ISO7762QDWRQ1

Overview

The ISO7762QDWRQ1 is an automotive-grade digital isolator from Texas Instruments, featuring six channels in a split configuration of four forward and two reverse paths. It utilizes capacitive coupling technology to provide robust signal isolation with a maximum 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. Key electrical parameters include a propagation delay of 11 ns, a typical operating supply current of 25.7 mA, and a pulse width distortion of 0.4 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments
• High common-mode transient immunity of 85 kV/µs ensures signal integrity in noisy power systems
• Capacitive coupling architecture provides galvanic isolation without magnetic core limitations
• Split channel configuration allows flexible bidirectional and unidirectional signal routing

Applications

• Automotive inverter control systems requiring high-speed isolated communication
• Motor drive interfaces for electric vehicles and hybrid powertrains
• On-board charger (OBC) gate driver feedback loops
• Battery management system (BMS) cell monitoring isolation

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade qualification and 'R' indicates reel packaging when sourcing. Ensure the component matches the SOIC-16 physical footprint and pinout configuration required by the target PCB layout. Cross-reference the manufacturer datasheet revision history to confirm compatibility with existing design files and regulatory certifications.

Selection Notes

Select this component when designing circuits that demand high-speed data transmission alongside robust electromagnetic interference resistance in automotive settings. The six-channel capacity reduces board space compared to discrete single-channel solutions. Consider the 5000 Vrms isolation rating for safety-critical applications separating high-voltage power stages from low-voltage control logic.

Part Context

This part belongs to the ISO776x family of automotive digital isolators, designed specifically for harsh electromagnetic environments found in modern electric and hybrid vehicles. It complements other Texas Instruments isolation products by offering a high-channel count solution in a compact package, addressing the increasing complexity of vehicle electronic architectures.

Replacement Considerations

Direct substitutes include the ISO7762QDBQRQ1 variant which shares identical electrical specifications but utilizes an SSOP-16 package instead of SOIC-16. Designers must verify pin-to-pin compatibility and thermal dissipation characteristics before swapping packages. Other family members like the ISO7720QDWRQ1 offer fewer channels and may not fit multi-channel requirements.
