Overview
The UCC23514SDWVR is a single-channel optically isolated gate driver from Texas Instruments, housed in an SOIC-8 package. It provides 5.0-kVrms reinforced isolation and features opto-compatible inputs for direct replacement of traditional optocouplers. The device delivers a peak source current of 4.5 A and a peak sink current of 5.3 A. Key electrical parameters include a maximum propagation delay of 105 ns, a rise time of 28 ns, and a fall time of 25 ns. It operates within a supply voltage range of 15 V to 30 V and supports junction temperatures from -40°C to +125°C.
Feature Summary
- Provides pin-to-pin compatibility with standard opto-isolated gate drivers for simplified design upgrades.
- Features opto-compatible input architecture enabling direct interfacing with common logic-level control signals.
- Delivers high peak output currents suitable for driving IGBTs, MOSFETs, and SiC MOSFETs efficiently.
Applications
- Industrial motor drives
- Inverter circuits
- Switch-mode power supplies
Procurement Notes
Verify the specific suffix 'SDWVR' corresponds to the SOIC-8 package and tape-and-reel packaging configuration. Confirm that the required isolation voltage rating of 5.0 kVrms meets the safety standards of the target application. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.
Selection Notes
Select this component when replacing legacy optocoupler-based gate drive solutions to improve switching speed and reduce propagation delay. Consider the 4.5-A source and 5.3-A sink capabilities for driving medium-power devices. Evaluate the SOIC-8 footprint constraints against available PCB space. Verify that the 15-V to 30-V supply range matches the available gate drive voltage rails.
Part Context
This part belongs to the UCC2351x family of optically isolated gate drivers designed by Texas Instruments. The series focuses on providing enhanced isolation performance while maintaining compatibility with existing optocoupler footprints. The UCC23514 specifically targets applications requiring higher current drive than lower-end variants offer.
Replacement Considerations
Officially documented as a pin-to-pin drop-in upgrade for many standard opto-isolated gate drivers. No specific substitute part numbers are publicly confirmed in the provided documentation.
