HX809RDBZRG from HANSCHIP semiconductor, in a SOT-23-3. 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	Chip ground reference.
2	RESET	output	Active-low reset output. Drives low when VCC falls below the threshold (Vth(E)=2.63 V for HX809R) and remains asserted for the internal power-on reset delay Trp (80-350 ms, typ. 200 ms) after VCC rises above the threshold. VOL <= 0.3 V at ISINK=1.2 mA; VOH >= 0.8*VCC at ISOURCE=500 uA.
3	VCC	power_in	Chip supply input and monitored voltage. Operating range 1.0 V to 6.0 V; absolute maximum 6.5 V. Quiescent current typ. 5.5 uA at VCC=6 V, no load.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hx809rdbzrg.step`	59 KB	You want the bare part, or you mark your own boards.
`hx809rdbzrg-etched.step`	2.2 MB	You want the part with `HX809RDBZRG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 534 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.
