Overview
Description
UCC23514SDWVR is TI’s isolated gate-driver device in the UCC2351x family. It provides an isolated drive signal to a MOSFET (or MOSFET pair in a half-bridge) used in high-voltage switch-mode power stages, enabling a controller on one side to switch the power side without a direct electrical connection.
Typical features (subject to datasheet): galvanic isolation between control and power domains, drive capability for MOSFETs, and protection/timing features such as undervoltage lockout and fault protection, plus dead-time control to prevent shoot-through. The SDWVR suffix indicates a specific packaging/revision variant; check the datasheet for exact details.
Common applications: offline or isolated switch-mode power supplies, flyback/ LLC converters, DC-DC converters, motor drives, and solar inverters.
For exact specifications (isolation rating, logic and output drive voltages, propagation delay, and protection thresholds), refer to the TI UCC23514SDWVR datasheet and product page. If you meant a different variant, please share the exact package/revision.

Equivalent
There is no guaranteed pin-for-pin drop-in equivalent. Comparable isolated MOSFET gate-driver families to consider: Silicon Labs Si827x/Si823x, Analog Devices ADuM413x/ADuM14xx, Infineon 1ED series, Broadcom/Avago ACPL driver families, and Renesas ISOW78xx. Verify isolation voltage, VCC range, output drive, timing, package/pinout and safety approvals before substituting.
