UCC5628FQPR/81540

Overview

The UCC5628FQPR/81540 is an automotive-grade, dual-channel digital isolator manufactured by Texas Instruments. It features a high-speed architecture with a typical propagation delay of 7 ns and a maximum data rate of 150 Mbps per channel. The device operates from a single supply voltage ranging from 3 V to 5.5 V for both the input and output sides. It provides robust isolation characteristics, including a reinforced isolation voltage rating and high common-mode transient immunity. Packaged in an 8-pin SOIC (D) surface-mount format, it is designed for reliable signal transmission in electric vehicle powertrains and industrial applications requiring galvanic isolation.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for long-term reliability
• Dual-channel configuration enabling independent signal isolation paths
• High common-mode transient immunity for noise-resistant operation in electric drive systems

Applications

• Electric vehicle traction inverters and motor control gate drivers
• On-board charger (OBC) and DC-DC converter isolated communication
• Industrial motor drives and servo systems requiring high-speed isolation

Procurement Notes

Verify the specific suffix /81540 against the manufacturer's official documentation to confirm reel size or tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade and temperature range for your target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require simultaneous bidirectional or unidirectional signal isolation with high-speed data integrity. Consider the 150 Mbps data rate limit and the 7 ns propagation delay when determining timing margins for your communication protocol. Verify that the operating voltage range aligns with your system's logic levels.

Part Context

This part belongs to the UCC56xx family of automotive digital isolators. It serves as a critical interface between low-voltage control circuits and high-voltage power stages. The family is characterized by its focus on electromagnetic interference (EMI) reduction and safety compliance in harsh electrical environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the UCC56xx series or other TI automotive isolators. Verify that any substitute matches the exact isolation voltage ratings, data rate capabilities, and AEC-Q100 qualification status.
