UCC27517DBVT is a Texas Instruments single-channel low-side gate driver in SOT-23-5, small tape and reel — for driving power MOSFETs and IGBTs from logic: SMPS, motor drives and inverters. 4 A/4 A drive with dual input in 5-pin SOT-23 is the selection point: flexible input gating in the smallest footprint. Selection advice: the DBVT suffix denotes SOT-23-5 in small tape and reel — the small-reel pick for prototypes and low-volume runs; for production volumes, the DBVR reel is the choice. 4.5 V to 18 V supply with 4 V UVLO. TI lists this part as ACTIVE. Parameters verified against the TI official product page.

UCC27517DBVT is a Texas Instruments single-channel high-speed low-side gate driver in SOT-23-5, tape and reel (250 per reel) — 4 A peak source and sink symmetrical drive, 4.5 V to 18 V supply, 13 ns typical propagation delay, −40 °C to +140 °C. Its dual-input design offers both IN+ (non-inverting) and IN− (inverting) on the same device, and the unused input can serve as the enable/disable control.
Against UCC27518DBVT: three real differences — (1) input structure: the 27517 configures as inverting or non-inverting via its dual inputs, while the 27518 is fixed inverting with a separate EN pin; (2) thresholds: the 27517 uses fixed TTL/CMOS-compatible thresholds independent of VDD with hysteresis, while the 27518's CMOS thresholds track VDD; (3) speed: 13 ns versus 17 ns typical. Pick the 27517 for logic-flexibility and threshold stability at low VDD.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. UCC27517DBVT names the SOT-23-5 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
Match the full ordering code, not the series name: package (SOT-23-5), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Texas Instruments datasheet before changing the BOM.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Tell us the full UCC27517DBVT order code, the maker (Texas Instruments), how many you need, reel or tray preference and acceptable date codes — one message is enough. Expect our quotation back within 24 hours.
