Each of the two independent, non-inverting channels delivers 4A peak source and 4A peak sink current, which means it can slam the gate of a large TO-220 or D2PAK FET through the Miller plateau without lingering in the linear region. The 20 ns rise and 15 ns fall times keep switching losses contained even when the load current is in the tens of amps. Supply range spans 4.5 V to 15 V, so it runs cleanly off a 5 V or 12 V bias rail — no extra regulator needed in most SMPS or motor-drive designs. ## Temperature grade and where it fits Rated for a junction temperature range of -55°C to 150°C, this part lands in the military-temperature band — it belongs in avionics power stages, downhole instrumentation, satellite DC-DC converters, or any environment where the ambient can swing past the usual -40°C industrial floor. The 8-SOIC package is a standard footprint; no exotic pad geometry, and the thermal performance through the leadframe is adequate for the 4A peak duty, provided the PCB copper area and via stitching are sized for the average dissipation. ## Lifecycle and sourcing posture TI lists the UCC37324DR as Active and ROHS3 compliant. No NRND flag, no last-time-buy notice — it remains a current-production line item suitable for new design-ins and volume builds. The laser etch and date-code consistency are part of our inbound inspection — every reel is checked for marking integrity before it leaves the dock. ## Genuine vs remarked — what to look for The 8-SOIC body is small enough that re-markers often sand the top surface and re-laser a premium date code. On the UCC37324DR, the original TI marking includes a two-line top mark: the first line reads 'UCC37324', the second carries the four-digit date-code and lot identifier. The laser etch on a genuine part has a consistent, shallow grey contrast — not a dark, burned-in look. If the package edge radius looks rounded or the marking is off-centre, that reel should go to X-ray before it hits the pick-and-place.","metaTitle":"UCC37324DR Low-Side Gate Driver, 4A Peak, 8-SOIC","metaDescription":"TI UCC37324DR low-side MOSFET driver: 4A peak source/sink, 20ns rise/15ns fall, 4.5V-15V supply, -55°C to 150°C.
