CN302 from ShangHai Consonance Elec, in a SOT-23-6. 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	FTH	input	Falling (lower) threshold input. Connect to an external resistor divider tapping the battery voltage. When VFTH falls below the internal 1.211V reference, /LBO goes low and LBO goes high after ~13µs delay. Input leakage ±10nA.
2	GND	power_in	Power ground (0V reference).
3	LBO	output	Active-high battery-low detect output, CMOS push-pull. Drives high when VFTH < Vref (battery low) and low when VRTH > Vref (battery OK). VOL ≤ 0.3V at ISINK=3.2mA (VCC=3V); VOH ≥ VCC-0.4V at ISOURCE=3mA.
4	VCC	power_in	Positive supply input. Operating range 1.9V to 6V; absolute max 6.5V. Typical supply current 9.5µA at VCC=3V.
5	/LBO	output	Active-low battery-low detect output (complement of LBO), CMOS push-pull. Drives low when VFTH < Vref (battery low) and high when VRTH > Vref (battery OK). VOL ≤ 0.3V at ISINK=3.2mA (VCC=3V); VOH ≥ VCC-0.4V at ISOURCE=3mA.
6	RTH	input	Rising (upper) threshold input. Connect to an external resistor divider tapping the battery voltage. When VRTH rises above the internal 1.211V reference, /LBO goes high and LBO goes low after ~12µs delay. Input leakage ±10nA.

3D model: SOT-23-6 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn302.step`	97 KB	You want the bare part, or you mark your own boards.
`cn302-etched.step`	1.3 MB	You want the part with `CN302` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 325 faces against 117 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.
