Overview
The UCC23514SDWV is a single-channel opto-compatible isolated gate driver featuring a 5.0-kVRMS isolation barrier and an e-diode input. It delivers a 4.5A source and 5.3A sink peak output current with a 12V to 33V supply range. Key electrical parameters include a maximum propagation delay of 105ns, minimum CMTI of 150kV/µs, and part-to-part delay matching of 25ns. The device operates from -40°C to +150°C junction temperature in an 8-pin SOIC package.
Feature Summary
- Pin-to-pin drop-in upgrade for standard opto-isolated gate drivers
- Enhanced reliability via e-diode input technology with superior aging characteristics
- High common-mode transient immunity (CMTI) for robust noise rejection
- Rail-to-rail output capability supporting bipolar power supplies
Applications
- Industrial motor control drives
- Solar inverters
- Industrial power supplies and UPS systems
- Induction heating systems
Procurement Notes
Verify the specific suffix 'SDWV' against the manufacturer's latest datasheet to confirm pinout and output configuration. Note that distributor listings may indicate this product as obsolete; check for active replacement parts or last-time buy status before finalizing procurement plans.
Selection Notes
Select this component when replacing legacy optocoupler-based drivers to improve CMTI and reduce propagation delay variance. The SDWV variant provides dual outputs (HIGH and LOW) suitable for applications requiring separate high-side and low-side drive signals or specific UVLO referencing configurations.
Part Context
This device belongs to the UCC23514 family of capacitive isolation gate drivers. It is designed to replace traditional optocouplers in IGBT, MOSFET, and SiC MOSFET driving applications. The family includes variants like UCC23514V (single-ended) and UCC23514M (Miller clamp), offering flexibility for different circuit topologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Distributor sources list this item as obsolete; consult Texas Instruments directly for current recommended replacements within the UCC235xx series.
FAQ
What is the difference between the UCC23514S and UCC23514V variants?
The UCC23514S version provides two independent output pins (OUTH and OUTL) for split-gate drive applications, whereas the UCC23514V offers a single-ended gate drive output.
How does the e-diode input improve reliability compared to traditional LEDs?
The e-diode input eliminates the degradation associated with traditional LED light intensity over time, ensuring consistent performance and extended isolation barrier life exceeding 50 years under normal operating conditions.
