EG27519 from EG Micro, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	EN	input	Chip enable input. When EN is low, OUT is forced low regardless of IN+. Internally pulled to VDD via 100k so the part is enabled when EN is left floating. Logic thresholds Vin(H) >= 2.5V, Vin(L) <= 1.0V; absolute max 20V.
2	GND	power_in	Device ground / return for the driver output current.
3	IN+	input	Non-inverting PWM logic input. When IN+ is high the OUT pin drives high; when low OUT drives low. Internally pulled to GND via 100k so OUT stays low if IN+ is left floating. Logic thresholds Vin(H) >= 2.5V, Vin(L) <= 1.0V; input current at Vin=5V typ <=100uA.
4	OUT	output	Gate driver output. Rail-to-rail push-pull stage capable of +/-4A peak source/sink at VDD=12V (PW<=10us). Typical Ton=80ns, Toff=60ns, Tr=40ns, Tf=20ns with CL=10nF. Connect through a small series gate resistor to the power MOSFET/IGBT gate.
5	VDD	power_in	Driver supply, 4V to 20V (typ 12V). Bypass to GND with a low-ESR capacitor placed close to the pin; the cap sources the peak gate charge during MOSFET turn-on. Quiescent current IQ ~150uA at VDD=12V with input floating.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`eg27519.step`	85 KB	You want the bare part, or you mark your own boards.
`eg27519-etched.step`	1.4 MB	You want the part with `EG27519` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 349 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
