UCC5640PWX

Overview

The UCC5640PWX is a high-speed, dual-channel digital isolator manufactured by Texas Instruments. It provides bidirectional signal isolation with integrated logic and gate drive functionality in a compact 16-pin PowerPAD SOIC package. The device supports data rates up to 150 Mbps per channel and operates with supply voltages ranging from 3.0 V to 5.5 V for both the isolated side (VISO) and the logic side (VIO). Key electrical parameters include a propagation delay of typically 8 ns, an isolation voltage rating of 5000 Vrms, and a common-mode transient immunity of ±100 kV/μs. The operating temperature range extends from -40°C to +125°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Integrated dual-channel digital isolation with independent input and output supplies
• High-speed data transmission capability supporting up to 150 Mbps per channel
• Robust electromagnetic interference immunity with high common-mode transient resistance
• Compact surface-mount packaging designed for efficient thermal management

Applications

• Industrial automation and control systems requiring galvanic isolation
• Power electronics interfaces including motor drives and inverters
• Medical equipment needing safety-certified signal isolation
• Communication interfaces in noisy electrical environments

Procurement Notes

Verify the specific suffix 'PWX' against the manufacturer's official datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure that the ordering information matches the exact package variant and moisture sensitivity level required for your assembly process. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when bidirectional isolation is required between microcontrollers and power stages. Consider the 150 Mbps data rate limit for high-speed communication needs. Evaluate the thermal performance of the PowerPAD package if operating near the upper temperature limits. Verify that the supply voltage requirements align with the system's available rails for both isolated and non-isolated domains.

Part Context

This device belongs to the UCC56xx family of high-speed digital isolators. It is designed to replace traditional optocouplers in applications demanding higher speed and better reliability. The family offers various channel configurations and package options to suit different isolation voltage and data rate requirements.

Replacement Considerations

Check for direct replacements within the UCC56xx series with compatible pinouts. Verify that any substitute maintains the same isolation voltage rating and data speed. Ensure thermal characteristics and package dimensions match the existing PCB layout constraints.
