5 A peak output — what it drives
The UCC27528DR is a dual low-side gate driver from TI, built to drive IGBT and N-Channel MOSFET gates with a 5 A peak source and sink current per channel. That 5 A rating means it can charge and discharge the gate capacitance of a large TO-247 IGBT or a parallel MOSFET bank fast enough to keep switching losses in check. The two channels are independent and non-inverting, so you can drive two separate half-bridge low-side devices or parallel them for higher current into a single gate.
7 ns rise, 6 ns fall — edge speed matters
Those edges are fast enough that the layout inductance between the driver output and the gate becomes the limiting factor — keep the trace short and wide, and place the driver close to the power device. The 4.5 V to 18 V supply range lets it run from a 5 V logic rail or a 12 V bias supply common in industrial drives.
140°C junction — where it survives
Operating junction temperature range from -40°C to 140°C. That 140°C ceiling is higher than the usual 125°C industrial limit, so this part fits applications where the driver sits on a hot PCB near the power stage — motor drives, DC-DC converters in enclosed boxes, or under-hood automotive auxiliary inverters.
