CN3063 from ShangHai Consonance Elec, in a SOIC-8-EP. 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	TEMP	input	Temperature Sense Input. Connect to NTC thermistor output in the battery pack. When TEMP voltage falls below 46% of VIN (or rises above) for more than 0.15 s, charging is suspended. Threshold typ. 46% of VIN; input current <=0.5 uA. Ground to disable temperature sensing.
2	ISET	passive	Constant Charge Current Setting and Charge Current Monitor Pin. Charge current is programmed by a resistor RISET from ISET to GND: ICH = (VISET/RISET) x 900. Regulated to 0.2 V in precharge mode and 2.0 V in constant-current mode.
3	GND	power_in	Ground terminal.
4	VIN	power_in	Positive Input Supply Voltage. Operating range 4.4 V to 6 V (abs max 6.5 V). When VIN drops to within 40 mV of VBAT the device enters low-power sleep mode, reducing BAT drain to <3 uA. UVLO threshold typ. 3.7 V (falling) with 0.1 V hysteresis.
5	BAT	power_out	Battery Connection Pin. Connect to positive terminal of Li-ion/Li-Polymer cell. Provides regulated 4.2 V (typ) charge output up to 600 mA. Draws <3 uA in chip-disable or sleep mode. Requires ~4.7 uF decoupling to GND.
6	DONE	output	Open-Drain Charge Termination Status Output (active-low, /DONE). Pulled low by internal switch when charge cycle terminates; otherwise high-impedance. Sink capability 10 mA; leakage <=1 uA at VDONE=6 V.
7	CHRG	output	Open-Drain Charge Status Output (active-low, /CHRG). Pulled low by internal switch while battery is being charged; high-impedance otherwise. Sink capability 10 mA; leakage <=1 uA at VCHRG=6 V.
8	FB	input	Battery Voltage Kelvin Sense Input. Kelvin-senses battery voltage at the cell; regulation voltage in constant-voltage mode can be adjusted above 4.2 V by connecting an external resistor Rx between FB and BAT (Vbat = 4.2 + 3.04e-6 x Rx).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn3063.step`	125 KB	You want the bare part, or you mark your own boards.
`cn3063-etched.step`	1.8 MB	You want the part with `CN3063` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 429 faces against 152 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.
