TPT7721-SOBR

Overview

The TPT7721-SOBR is a dual-channel enhanced digital isolator from the TPT772x series, manufactured by 3PEAK. It features a 16-pin Wide SOIC (WSOP16) package and supports data rates up to 150 Mbps with a typical common-mode transient immunity of ±150 kV/μs. The device operates on a wide supply voltage range of 2.25 V to 5.5 V and offers an isolation rating of 5000 VRMS per UL 1577 standards. It includes ESD protection exceeding JESD 22 Human Model ±6 kV and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel enhanced digital isolation architecture
• High-speed data transmission capability up to 150 Mbps
• Robust electromagnetic compatibility with high common-mode transient immunity
• Wide operating supply voltage range for flexible system integration

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring
• Automotive electronic subsystems

Procurement Notes

Verify the specific suffix 'SOBR' corresponds to the 16-pin WSOP package configuration. Confirm that the required isolation certification level matches your system's safety standards, as ratings vary between SOP and WSOP packages. Ensure the ordering part number aligns with the desired output logic state defaults specified in the official datasheet.

Selection Notes

Select this component when dual-channel isolation is required in space-constrained applications utilizing the WSOP16 footprint. It is suitable for designs needing high CMTI performance and wide supply voltage tolerance. Compare against SOP8 variants if lower isolation ratings or smaller footprints are acceptable for the specific application constraints.

Part Context

This device belongs to the TPT772x family of high-performance digital isolators. The series provides enhanced isolation capabilities certified under multiple international safety standards including UL, VDE, and CSA. The TPT7721 variant specifically offers two independent channels for bidirectional or unidirectional signal transmission.

Replacement Considerations

Direct substitutes include other models within the TPT772x series such as TPT7721-SO1R, noting the package difference between WSOP16 and SOP8. Cross-reference pinouts and isolation ratings carefully when considering alternative manufacturers' dual-channel isolators.
