Product details

Single low-side driver for 4A gate drive in a SOT-23-5

The Texas Instruments UCC27518DBVR is a single-channel low-side gate driver rated for 4A peak source and 4A peak sink current, packaged in a SOT-23-5. It drives N-channel MOSFETs and IGBTs with a typical rise time of 8ns and fall time of 7ns, keeping switching losses low in hard-switched converters. The inverting input simplifies the interface when the PWM controller output is active-high — no extra inverter needed on the board. Supply range spans 4.5V to 18V, covering both 5V and 12V bias rails common in industrial power supplies, motor drives, and telecom DC-DC converters. Junction temperature rating of -40°C to 140°C allows deployment in motor-drive cabinets and under-hood automotive environments without derating.

Frequently asked questions

UCC27518DBVR vs UCC27517DBVR — what are the differences?

The UCC27517DBVR is the non-inverting version of the same driver family. The UCC27518DBVR has an inverting input, so the logic polarity is reversed. Both share the same 4A peak, 8ns/7ns rise/fall, and SOT-23-5 package. Choose the inverting version when the controller output is active-high.
