TPT7721F-SOBR

Overview

The TPT7721F-SOBR is a dual-channel enhanced digital isolator from 3PEAK, housed in a 16-pin Wide SOIC (WSOP16) package. It features a 5000 Vrms isolation rating per UL 1577 and supports data rates up to 150 Mbps. The device offers typical common-mode transient immunity of ±150 kV/μs and low propagation delay of 12 ns. Operating on a wide supply voltage range of 2.25 V to 5.5 V, it ensures default high output states. Certified under VDE, UL, CSA, TUV, and CQC standards for safety applications.

Feature Summary

• Provides 5000 Vrms reinforced insulation capability suitable for safety-critical designs
• Delivers high-speed data transmission with 150 Mbps rate and low propagation delay
• Ensures robust noise immunity with high common-mode transient rejection
• Includes comprehensive global safety certifications for industrial and medical use

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment adhering to IEC 60601-1 standards
• Digital communication interfaces such as RS-485 and CAN bus
• Power electronics control circuits with high voltage separation needs

Procurement Notes

Verify the specific suffix SOBR corresponds to the WSOP16 package variant when sourcing. Confirm that the F designation indicates the default high-output logic state required by your circuit design. Ensure compliance with relevant regional safety standards such as VDE or UL before final integration. Check for updated certification documents directly from 3PEAK to validate current approval status for your target market.

Selection Notes

Select this component when dual-channel isolation with 5000 Vrms rating is mandatory. It is suitable for applications demanding high speed up to 150 Mbps alongside strict safety compliance. Consider the WSOP16 package for wider creepage distances compared to standard SOP8 variants. Verify power supply compatibility within the 2.25 V to 5.5 V range during system design.

Part Context

This part belongs to the TPT772x series of high-performance digital isolators. It complements other variants like TPT7721-SO1R which offer lower isolation ratings in smaller packages. The series provides options for different channel counts and package types to meet diverse space and performance requirements in modern electronic systems.

Replacement Considerations

Direct substitutes include TPT7721-SOBR for identical functionality in the same package. TPT7721-SO1R serves as an alternative if lower isolation ratings are acceptable. Cross-reference with TPT7320F-SO1R for similar pinouts but verify logic polarity differences carefully.
