It drives both N-channel MOSFETs and IGBTs with a supply range of 4.5V to 18V. The driver accepts inverting or non-inverting input signals, giving the designer flexibility in polarity. ## Logic compatibility and temperature grade Logic thresholds are set at 1V (VIL) and 2.4V (VIH), so the driver interfaces directly with 3.3V or 5V logic without external level shifters. Compared to the LM5106MM/NOPB, which is a half-bridge driver with 1.2A peak output and a 125°C temperature limit, the UCC27517DBVT delivers higher peak current (4A vs 1.2A) and a wider junction temperature range (140°C vs 125°C), but is single-channel and low-side only. ## Active production, SOT-23-5 package The SOT-23-5 package is a five-pin small-outline transistor footprint.","metaTitle":"UCC27517DBVT Gate Driver – TI, 4A Peak, SOT-23-5","metaDescription":"Texas Instruments UCC27517DBVT low-side gate driver: 4A peak source/sink, 4.5V-18V supply, 8ns/7ns rise/fall, SOT-23-5.

The supply range of 4.5V to 18V covers 5V gate-drive rails, and the 4A peak source current charges the gate capacitance quickly. The logic thresholds of 1V / 2.4V are compatible with 5V logic outputs."},{"question":"Is UCC27517DBVT compatible with 5V logic?","answer":"Yes. The VIH threshold is 2.4V, so a 5V logic high is well above the threshold. The VIL threshold is 1V, providing noise margin for low-level signals."},{"question":"What is the closest functional second-source to UCC27517DBVT?","answer":"The LM5106MM/NOPB is a half-bridge driver with 1.2A peak output and a 125°C junction limit. It is not a direct pin-for-pin replacement — the UCC27517DBVT is single-channel low-side with higher current (4A) and wider temperature range (140°C).
