Single-channel 4A gate driver in SOT-23-5
The UCC27517DBVT is a single-channel low-side gate driver from Texas Instruments, rated for 4A peak source and 4A peak sink current. 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.
