Its headline spec is the asymmetric peak output: 2.5 A source and 5 A sink. That means the gate discharges faster than it charges, which directly reduces the turn-off switching loss and shrinks the dead-time you need between high-side and low-side transitions in a half-bridge. The 15 ns typical rise and 7 ns typical fall times back up the current asymmetry — the part is designed for switching frequencies in the tens to hundreds of kHz, typical for SMPS, DC-DC converters, and motor-drive gate drive stages. ## Supply range and logic interface Supply voltage spans 10 V to 32 V, covering the common bias rails for IGBT gate drive (typically 12 V to 15 V) and allowing the same part to work across 12 V, 24 V, and 48 V bus systems without a separate regulator. ## Thermal and package reality The 140 °C ceiling means this driver can sit next to hot IGBTs or MOSFETs on a crowded power stage without needing a separate heatsink or thermal relief slot — the SOT-23-6 package relies on the PCB copper pour for heat spreading. The SOT-23-6 footprint is compact — 2.9 mm × 1.6 mm typical body size. The land pattern is standard for this package; no exposed thermal pad, so the junction-to-ambient thermal resistance depends on the copper area on the board.","metaTitle":"UCC27531DBVR Gate Driver, 2.5A/5A Peak, SOT-23-6","metaDescription":"UCC27531DBVR low-side gate driver from TI drives IGBT and N-channel MOSFET gates. 2.5A source, 5A sink peak output. 10V to 32V supply.
