TPT7740-SOBR

Overview

The TPT7740-SOBR is a high-performance, four-channel digital isolator manufactured by 3PEAK. It provides robust signal isolation with a 5000-VRMS isolation rating per UL 1577 and a typical common-mode transient immunity (CMTI) of 150 kV/µs. The device supports data rates up to 150 Mbps and operates within a supply voltage range of 2.7 V to 5.5 V. Packaged in a 16-pin WSOP format, it ensures reliable communication across isolated boundaries in demanding industrial and automotive environments.

Feature Summary

• Four independent channels for simultaneous bidirectional or unidirectional signal transmission
• High common-mode transient immunity ensuring noise resilience in electrically noisy environments
• Wide operating temperature range suitable for harsh industrial conditions
• Compliance with international safety standards including UL, CSA, and VDE certifications

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Automotive electronic control units (ECUs) for safe data exchange across isolation barriers
• Medical equipment needing certified isolation for patient safety compliance
• Power conversion circuits such as inverters and motor drives

Procurement Notes

Verify the specific suffix 'SOBR' corresponds to the required package type and tape-and-reel quantity. Confirm that the 5000-VRMS rating meets your system's safety clearance requirements. Check for RoHS compliance status if restricted substances are a concern. Ensure the datasheet version matches your design specifications regarding pinout and electrical characteristics.

Selection Notes

Select this component when four isolated channels are necessary within a single footprint. Consider the 150 Mbps data rate against your application's bandwidth needs. Evaluate the 150 kV/µs CMTI against local electromagnetic interference levels. Compare the 5000-VRMS rating with other available isolation ratings to ensure adequate safety margins for your specific voltage isolation requirements.

Part Context

This part belongs to the TPT774x family of digital isolators from 3PEAK. The family offers various channel counts and isolation ratings. The TPT7740 specifically focuses on four-channel applications. It complements 3PEAK's broader portfolio of signal chain and mixed-signal products designed for industrial and automotive markets.

Replacement Considerations

Check for direct substitutes within the TPT774x series that may offer different isolation voltages or package options. Verify pin-to-pin compatibility with existing designs before switching. Consult official manufacturer documentation for any updated revisions or recommended alternative parts.
