ISO7762FQDWRQ1

Overview

The ISO7762FQDWRQ1 is an automotive-grade, six-channel digital isolator from Texas Instruments' ISO776x-Q1 series. It features a 4/2 channel configuration (four forward, two reverse) with bidirectional or unidirectional polarity options. The device utilizes capacitive coupling for isolation and supports data rates up to 100 Mb/s. Key electrical parameters include a maximum propagation delay of 11 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.4 ns. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical operating current of 25.7 mA. The component provides reinforced insulation ratings of 5000 Vrms per UL 1577 standards. It is housed in a 16-pin SOIC (DW) package and is qualified under AEC-Q100 for temperatures ranging from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments.
• Reinforced isolation architecture providing high electromagnetic compatibility (EMC) immunity.
• High-speed signal transmission capability supporting data rates up to 100 Mb/s.
• Six-channel integration with flexible 4/2 channel directionality for complex system designs.

Applications

• Automotive gateway systems requiring isolated communication between domains.
• Inverter control circuits in electric and hybrid vehicles.
• Battery management systems (BMS) with isolated sensor interfaces.
• Charging station controllers needing galvanic isolation for safety compliance.

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade qualification and 'DW' indicates the 16-pin SOIC package. Ensure the order matches the required isolation rating of 5000 Vrms associated with this package type. Confirm that the manufacturer is Texas Instruments to guarantee authenticity. Check for RoHS compliance status as indicated in official documentation. Validate that the component meets the specified temperature range for your application environment.

Selection Notes

Select this component when automotive certification is mandatory and high channel density is required. The 5000 Vrms rating suits applications demanding reinforced isolation barriers. Consider the 100 Mb/s speed limit for bandwidth requirements. The 16-pin SOIC package offers a compact footprint compared to wider SOIC variants. Evaluate power consumption needs against the 25.7 mA typical current draw. Ensure the system design accommodates the bidirectional/unidirectional flexibility of the channels.

Part Context

This part belongs to the ISO776x-Q1 family of high-performance digital isolators designed specifically for automotive electronics. The family shares core technologies but varies by package and isolation rating. The DW package variant distinguishes itself with a higher 5000 Vrms reinforced isolation rating compared to other packages in the series. It serves as a critical interface component for maintaining signal integrity while ensuring electrical safety in high-voltage automotive networks.

Replacement Considerations

Direct substitutes within the same family include ISO7762QDBQRQ1, though it uses a different SSOP-16 package and has a 3000 Vrms rating. Other ISO776x-Q1 devices may serve as functional alternatives if pinout and isolation requirements align. Verify package dimensions and thermal characteristics before swapping. Ensure any replacement maintains the AEC-Q100 qualification status for automotive use.
