• Delivers high peak drive currents of 1.5 A source and 2 A sink for efficient switching control
• Supports operation across an extended industrial temperature range from -40°C to 125°C

Applications

• Industrial motor drives
• Inverters and converters
• Switch-mode power supplies

Procurement Notes

Verify the specific suffix BDWYR corresponds to the tape-and-reel packaging variant when ordering. Confirm that the 6-SOIC footprint matches the target PCB layout. Ensure the design accounts for the 5.7-kVRMS isolation voltage requirements relative to system safety standards. Cross-reference the manufacturer datasheet for precise electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when replacing legacy optocoupler-based gate drivers to improve speed and reliability. Choose the UCC23511BDWYR for applications requiring 5.7-kVRMS isolation with a standard SOIC-6 footprint. Consider the 1.5 A source and 2 A sink drive strength for medium-power IGBT or MOSFET switching. Verify compatibility with the control logic voltage levels due to the opto-compatible input architecture.

Part Context

This part belongs to the UCC2351x family of single-channel isolated gate drivers designed by Texas Instruments. The series focuses on providing high-performance isolation with pin-to-pin compatibility for existing optocoupler designs. The UCC23511 variant specifically targets applications needing moderate drive current with robust isolation capabilities in a compact surface-mount package.
