The Texas Instruments UCC27517ADBVR is a single-channel low-side gate driver for IGBTs and N-Channel MOSFETs. It delivers 4A peak source and 4A peak sink current from a 4.5V to 18V supply.
The 4A peak source and sink rating determines gate charge switching speed. Rise and fall times are 8ns and 7ns typical.
The -40°C to 140°C junction temperature rating covers industrial and automotive environments.
Yes. The logic input thresholds are 1V VIL and 2.4V VIH, so a 5V logic output with a typical VOH of 4.5V to 5V drives the input high reliably. 3.3V logic also works since 3.3V VOH exceeds the 2.4V VIH threshold.
Yes. The UCC27517ADBVR is specified for IGBT and N-Channel MOSFET gates. The 4A peak source and sink current can drive typical IGBT gate charges up to several hundred nC, depending on switching frequency and acceptable switching speed.
