It delivers 4A peak source and 4A peak sink current from a supply range of 4.5V to 18V, with an inverting input configuration — the output goes high when the input is low. The 8ns rise and 7ns fall times (typical) allow fast gate charging, reducing switching losses in hard-switched topologies. The SOT-23-5 package (SC-74A) keeps the board footprint small, suitable for compact power supplies and motor drives.
It is an inverting driver — the output is high when the input is low. This matches controllers that use active-low PWM logic.
The UCC27518 has an inverting input; the UCC27517 has a non-inverting input. Both are single-channel 4A low-side drivers in the same package and supply range. The choice depends on the polarity of the upstream PWM signal.
The UCC27519 is a dual-input (AND) version that allows enable/shutdown control via a second input. The UCC27518 is a single inverting input only. Both share the same 4A peak drive and SOT-23-5 package.
No — the UCC27518DBVT has an inverting input, while the UCC27517DBVT is non-inverting. They are not pin-compatible for a drop-in swap unless the controller logic is also inverted.
