ISO7762FQDBQQ1

Overview

The ISO7762FQDBQQ1 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 operating at data rates up to 100 Mb/s. The device utilizes capacitive coupling technology to provide reinforced isolation with an insulation voltage of 5000 Vrms. It operates within a supply voltage range of 2.25 V to 5.5 V and supports bidirectional or unidirectional signal transmission. Key electrical parameters include a maximum propagation delay of 11 ns, typical rise and fall times of 3.9 ns, and a pulse width distortion of 0.4 ns. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) performance suitable for demanding automotive environments.
• Offers high common-mode transient immunity to ensure reliable signal integrity in noisy systems.
• Integrates six isolated channels in a compact SSOP-16 package to reduce board space.
• Supports flexible channel configurations with both bidirectional and unidirectional polarity options.

Applications

• Automotive body control modules requiring multi-channel isolation
• Inverter gate drive circuits in electric vehicles
• On-board charger (OBC) communication interfaces
• Battery management system (BMS) isolation barriers

Procurement Notes

Verify the specific suffix 'FQ' against the manufacturer's current datasheet to confirm exact configuration and packaging details. Ensure the component meets the required AEC-Q100 grade specifications for your target automotive application. Cross-reference the SSOP-16 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a high-density six-channel solution is required for automotive systems. Compare the 100 Mb/s data rate against application bandwidth needs. Evaluate the 5000 Vrms insulation rating against system voltage requirements. Consider the 2.25 V to 5.5 V supply range for power budget constraints. Assess the thermal dissipation characteristics relative to the enclosure design.

Part Context

This part belongs to the ISO776x-Q1 family of high-speed digital isolators. It shares the same core isolation architecture as other members like the ISO7762QDBQRQ1 but differs in packaging and specific ordering suffixes. The family is characterized by its robust EMC performance and suitability for harsh automotive electrical environments.

Replacement Considerations

The ISO7762QDBQRQ1 serves as a parameter-equivalent alternative within the same product family. Verify that the package type and pinout remain compatible before substitution. Confirm that the replacement part maintains the required AEC-Q100 qualification status.
