Overview
The ISO7730FQDBQQ1 is an automotive-grade, reinforced triple-channel digital isolator from Texas Instruments. It features a 16-lead SSOP package and operates on a supply voltage range of 2.25 V to 5.5 V. The device provides unidirectional signal isolation with a data rate of 100 Mb/s and a maximum propagation delay of 11 ns. It supports an insulation voltage of 3000 Vrms and withstands common-mode transients up to 85 kV/µs. Operating temperatures range from -40°C to +125°C, and it consumes 17.5 mA of operating supply current.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments.
- Reinforced insulation architecture providing high-voltage isolation capabilities for safety-critical applications.
- High-speed data transmission capability ensuring low latency and precise signal integrity across channels.
Applications
- Automotive gateway systems requiring isolated communication between domains.
- On-board charger (OBC) control circuits for electric vehicles.
- Battery management systems (BMS) within automotive platforms.
Procurement Notes
Verify the specific suffix 'FQ' confirms the required automotive grade and package configuration. Ensure compatibility with the target PCB footprint for the 16-lead SSOP variant. Confirm that the 3000 Vrms insulation rating meets the system's safety isolation requirements. Validate that the -40°C to +125°C temperature range aligns with the operational environment specifications.
Selection Notes
Select this component when automotive certification is mandatory for digital isolation needs. It is suitable for designs requiring three independent unidirectional channels with high common-mode transient immunity. Consider this part over non-automotive variants if long-term reliability in harsh vehicular conditions is a priority. Ensure the 100 Mb/s data rate suffices for the intended bus protocols.
Part Context
This device belongs to the ISO7730-Q1 family of high-speed digital isolators designed specifically for automotive electronics. It utilizes capacitive coupling technology to provide galvanic isolation between circuit sections. The series is engineered to meet stringent electromagnetic compatibility (EMC) standards prevalent in modern vehicle architectures.
Replacement Considerations
ISO7730QDBQRQ1: Similar automotive triple-channel isolator but offers 2500 Vrms insulation instead of 3000 Vrms.
