What this driver brings to the half-bridge
The Texas Instruments UCC27516DRSR is a single-channel low-side gate driver for IGBT and N-Channel MOSFET gates.
4A peak drive — what it means for your switching cell
The 4 A peak source and sink current is the rating that decides whether this driver can turn on your chosen power switch within your dead-time budget.
Package and thermal reality
The 6-SON (3x3 mm) is a surface-mount package with a thermal pad underneath.
There is no NRND or EOL flag on this part, so it remains a current-design-in candidate for new builds. The base product number is UCC27516; density and package variants share the same driver core, so a move to a different package or channel count within the family keeps the same drive characteristics.
