Overview
The UCC21540DWKR is a reinforced isolation dual-channel gate driver from Texas Instruments, housed in a SOIC-16 (DWK) package. It provides galvanic isolation with a maximum propagation delay of 40 ns, rise time of 16 ns, and fall time of 12 ns. The device supports peak source currents up to 4A and peak sink currents up to 6A. Operating temperatures range from -40°C to +125°C, with a power dissipation rating of 915 mW.
Feature Summary
- Reinforced isolation capability for high-voltage applications
- Dual-channel architecture with programmable deadtime
- Wide body package options for enhanced channel-to-channel spacing
Applications
- Industrial motor drives
- Inverter systems
- Switched-mode power supplies
Procurement Notes
Verify the specific suffix 'DWKR' confirms the SOIC-16 package and tape-and-reel shipping format. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for automotive use. Cross-reference datasheet revision levels to confirm pinout compatibility with target PCB footprints before finalizing procurement orders.
Selection Notes
Select this component when reinforced isolation and dual-channel control are required. The wide-body SOIC-16 package facilitates higher creepage distances compared to standard packages. Consider the 4A/6A drive strength for medium-power switching applications. Verify input logic compatibility with CMOS or TTL standards during system design integration.
Part Context
This part belongs to the UCC2154x family of isolated gate drivers. It shares functional similarities with the UCC21520 but offers distinct package and isolation features. The DWK variant specifically addresses spacing requirements between channels, making it suitable for compact high-voltage designs where standard SOIC-16 dimensions are insufficient.
Replacement Considerations
The UCC21520 is a related device within the same family. Verify package pinout differences and isolation voltage ratings before substitution. Ensure replacement parts match the specific thermal and electrical performance requirements of the original design.
FAQ
What is the channel-to-channel spacing for the UCC21540DWKR?
The DWK package variant provides 3.3 mm channel-to-channel spacing.
Does the UCC21540 support programmable deadtime?
Yes, the device includes programmable deadtime functionality to prevent shoot-through in bridge configurations.
