UCC21540QDWKRQ1

Overview

The UCC21540QDWKRQ1 is an automotive-grade, galvanically isolated dual-channel gate driver from Texas Instruments. It features a 5.7 kVRMS isolation rating and operates within a wide temperature range of -40°C to +150°C. The device provides a peak output current of 4A source and 6A sink. Key electrical parameters include a maximum propagation delay of 40 ns, rise time of 16 ns, and fall time of 12 ns. It is housed in a SOIC-16 package.

Feature Summary

• Galvanic isolation with 5.7 kVRMS rating for robust noise immunity
• Programmable dead-time control to prevent shoot-through in power stages
• Wide operating temperature range ensuring stability in extreme conditions
• Dual-channel architecture supporting high-side and low-side switching

Applications

• Automotive motor drives
• Inverter systems
• High-voltage DC/DC converters

Procurement Notes

Verify the specific suffix 'QDWKRQ1' against the official datasheet to confirm the SOIC-16 package, reel packaging, and AEC-Q100 qualification status. Ensure compatibility with system voltage levels and thermal requirements before procurement.

Selection Notes

Select this component for applications requiring reinforced isolation and precise timing control. The programmable dead-time feature distinguishes it from standard drivers, making it suitable for complex bridge topologies where shoot-through prevention is critical.

Part Context

This part belongs to the UCC21540-Q1 family of isolated gate drivers. It shares architectural similarities with other devices in the series but is specifically qualified for automotive use. The Q1 designation indicates compliance with automotive reliability standards.

Replacement Considerations

Direct substitutes may include other UCC21540 variants with different package options or insulation ratings. Verify pinout compatibility and isolation voltage specifications when considering alternatives.
