CN3768 from ShangHai Consonance Elec, in a SOP-8. 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	VG	power_out	Internal voltage regulator output. Supplies power to the internal gate-driver circuit. A 100nF capacitor must be connected between VG and VCC.
2	GND	power_in	Ground. Negative input of the input supply and negative terminal of the battery.
3	CHRG	output	Charge status indicator, open-drain output (active-low, denoted /CHRG). Internal transistor pulls the pin low during trickle, constant-current, and over-charge modes; otherwise the pin is high-impedance. Pull-down current typically 12mA at VCHRG=1V; leakage 1uA max at VCHRG=25V.
4	COM	input	Loop compensation input. Connect a 120Ω resistor in series with a 220nF capacitor from this pin to GND to stabilize the current and voltage regulation loops. Absolute max 6.5V to GND.
5	BAT	input	Battery positive-terminal connection and negative input of the charge-current sense. Connects to the battery '+' terminal; together with CSP it senses the voltage across the current-sense resistor RCS for current regulation. Typical BAT-pin current draw ~10uA at VBAT=12V.
6	CSP	input	Positive input of the charge-current sense. Together with BAT it senses the voltage across the external current-sense resistor RCS; constant-current charging current ICH = 0.12V / RCS.
7	VCC	power_in	External positive supply input; also powers the internal circuitry. Requires a decoupling/filter capacitor to GND. Operating input range 6.6V to 30V; UVLO typ 5.2V.
8	DRV	output	Gate-drive output for the external P-channel MOSFET. Low level is clamped to (VCC − 6.5V typ, max 8V below VCC), enabling use of low-Vgs P-channel FETs. Rise/fall times typ 40ns into 2nF.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn3768.step`	122 KB	You want the bare part, or you mark your own boards.
`cn3768-etched.step`	1.6 MB	You want the part with `CN3768` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 394 faces against 147 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.
