UCC27518DBVT 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 inverting input and enable in 5-pin SOT-23 is the selection point: active-low drive with shutdown control 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.

UCC27518DBVT is a Texas Instruments single-channel low-side gate driver with inverting input 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, 17 ns typical delay, and an enable pin that may float. Note the input threshold behavior: it is CMOS with thresholds that track VDD (VIH ≈ 55% VDD, VIL ≈ 39% VDD), unlike the fixed-threshold UCC27524 — at low VDD with 3.3 V logic, verify the threshold margin in the datasheet.
DBVT vs DBVR is purely a reel-quantity difference (250 vs 3000 per reel) — same die, same SOT-23-5. The non-inverting twin is UCC27519. Against UCC27517DBVT: the 27517 gives you dual IN+/IN− inputs (either polarity, fixed TTL/CMOS thresholds, 13 ns), while this 27518 is fixed inverting input with VDD-tracking CMOS thresholds and 17 ns delay. Pick this code for single-channel drive in space-constrained layouts where one inverting channel is exactly what the controller needs.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
The suffixes in UCC27518DBVT are not decoration — each one pins down the orderable configuration: SOT-23-5 package plus the grade and packing the code was qualified for. Treat any code that differs by a single suffix character as a different device and quote the full code exactly as printed on your 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.
The package (SOT-23-5) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
To request a quotation for UCC27518DBVT, send the full ordering code, manufacturer (Texas Instruments), quantity, packing format and date-code needs in one RFQ. Every RFQ gets a reply within 24 hours.
