SSP809C293NR from Shanghai Siproin Microelectronics, in a SOT-23. 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	GND	power_in	Ground reference pin (Vss). Connect to system ground.
2	VIN	power_in	Input voltage / monitored supply pin. Operating range 1.2V to 7.5V; absolute max -0.3V to 8.0V. This is the voltage being supervised against the VDET threshold (2.93V typ for this variant).
3	Vout/Reset	output	Active-low reset output. CMOS push-pull output (C variant). Asserted low when VIN falls below VDET (2.93V typ) and remains low for a 200ms timeout period after VIN rises back above the threshold.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ssp809c293nr.step`	59 KB	You want the bare part, or you mark your own boards.
`ssp809c293nr-etched.step`	2.8 MB	You want the part with `SSP809C293NR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 faces against 69 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.
