CN810L from ShangHai Consonance Elec, 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	Ground reference for the device.
2	RESET	output	Active-HIGH CMOS reset output. Driven HIGH when VCC is below the 4.63 V reset threshold (reset asserted). After VCC rises above VRES + VHYST, RESET remains HIGH for at least 140 ms (240 ms typ, 400 ms max) before transitioning LOW. Output can source ≥1.2 mA (VCC=3V) at VOH=VCC-0.4V and sink ≥3.2 mA (VCC=3V) at VOL=0.3V.
3	VCC	power_in	Positive supply input. This pin provides operating power AND is the monitored voltage. Absolute max 6.0 V, operating range up to 5.5 V (VCCMAX), reset output remains valid down to 1.15 V (VCCMIN). Typical supply current 3.2 µA at 3.0 V. A 0.1 µF bypass capacitor near this pin is recommended to improve rejection of short supply dips.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn810l.step`	59 KB	You want the bare part, or you mark your own boards.
`cn810l-etched.step`	1.2 MB	You want the part with `CN810L` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 287 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.
