ISO7762QDBQRQ1

Overview

The ISO7762QDBQRQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features four forward and two reverse channels in a 16-SSOP package. The device supports data rates up to 100 Mb/s with a propagation delay of 11 ns. It operates on a supply voltage range of 2.25 V to 5.5 V and provides an insulation voltage of 5000 Vrms. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) performance suitable for demanding automotive environments.
• Utilizes capacitive coupling technology to ensure high-speed signal transmission across isolation barriers.
• Offers configurable channel polarity supporting both bidirectional and unidirectional data flow.

Applications

• Automotive electronic control units requiring reinforced isolation
• Inverter gate drive circuits
• Industrial communication interfaces

Procurement Notes

Verify the specific suffix 'RQ1' confirms AEC-Q100 automotive qualification and the 'DBQ' indicates the 16-SSOP package variant. Ensure the design accounts for the 5000 Vrms insulation rating per UL 1577 standards. Confirm that the 100 Mb/s data rate meets system timing requirements before finalizing procurement specifications.

Selection Notes

Select this component when six isolated channels are required in a compact SSOP footprint. It is appropriate for designs needing high common-mode transient immunity and reinforced isolation ratings. Compare against lower channel count variants if fewer signals require isolation. Consider power consumption levels relative to the 25.7 mA operating current specification.

Part Context

This part belongs to the ISO776x-Q1 family of high-performance digital isolators. It shares the same functional architecture as other members but differs in channel configuration and isolation voltage ratings. The DBQ package variant specifically offers 5000 Vrms isolation compared to the 3000 Vrms rating found in other package options within the series.

Replacement Considerations

ISO7762FDBQRQ1 is a documented parameter-equivalent substitute within the same product family.
