UCC5620FQP

Overview

The UCC5620FQP is a high-speed, automotive-grade digital isolator manufactured by Texas Instruments. It features a single-channel architecture with a unidirectional signal path and an integrated low-power oscillator for data transmission without an external clock. The device operates within a supply voltage range of 3V to 5.5V for both the input and output sides. It provides electrical isolation rated at 5000 Vrms for one second, ensuring robust noise immunity in harsh environments. The component is housed in a 8-pin SOIC (N) package and is qualified for operation across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications
• Integrated low-power oscillator eliminates the need for external clock generation circuitry
• High common-mode transient immunity ensures accurate signal transmission under rapid voltage changes

Applications

• Motor control systems requiring isolated gate drive signals
• Inverter and converter topologies in electric vehicles
• Industrial automation interfaces demanding galvanic isolation

Procurement Notes

Verify the specific suffix 'FQP' to confirm the tape-and-reel packaging format and lead-free composition. Ensure the order includes the correct package variant matching the PCB footprint requirements. Confirm that the supplier sources directly from authorized channels to guarantee authenticity and traceability for automotive compliance.

Selection Notes

Select this component when a single-channel isolated interface is required for automotive power electronics. Compare against the UCC5620Q model if non-automotive grade specifications are sufficient for the application. Consider the propagation delay characteristics relative to the switching frequency of the target system to ensure timing accuracy.

Part Context

This part belongs to the UCC562x family of automotive digital isolators. It shares architectural similarities with other members like the UCC5621 but differs in channel count and directionality. The family is designed to replace traditional optocouplers in high-speed automotive networks, offering superior performance and longevity.

Replacement Considerations

Publicly confirmed direct substitutes include the UCC5620Q for non-automotive contexts. Verify pin compatibility before replacing legacy optocouplers or older isolator models. Consult official cross-reference lists for updated revisions.
