CN3763 from ShangHai Consonance Elec, in a SSOP-10-150mil. 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 linear regulator output that powers the internal gate-driver circuitry. Requires a 100nF decoupling capacitor between VG and VCC.
2	GND	power_in	Ground. Return for input supply and battery negative terminal.
3	CHRG	output	Charge status indication, open-drain output (active low). Internal transistor pulls low during charging; high-impedance otherwise. Typical pull-down current ~12mA at V_CHRG=1V; leakage <1uA at 30V.
4	DONE	output	Charge-complete indication, open-drain output (active low). Internal transistor pulls low when charging has finished; high-impedance otherwise. Typical pull-down current ~12mA at V_DONE=1V.
5	COM	passive	Loop compensation input. Connect a series 120Ω resistor and 220nF capacitor from COM to GND. Absolute-max voltage -0.3V to 6.5V.
6	FB	input	Battery-voltage feedback input. Senses the positive battery terminal to regulate the 12.6V CV setpoint. An optional resistor Rx between FB and BAT raises V_REG (V_REG = 12.6 + 8.996e-6 × Rx).
7	BAT	input	Battery positive connection and negative side of current-sense resistor. Connects to the battery pack '+' terminal; together with CSP it measures the voltage across Rcs (120mV typical) to regulate charge current.
8	CSP	input	Positive side of the charge-current sense input. Measures the voltage across Rcs between CSP and BAT (Ich = 120mV / Rcs) for current-mode regulation.
9	VCC	power_in	External input power positive terminal and internal-circuit supply (6.6V to 30V). Requires a bypass/decoupling capacitor from VCC to GND.
10	DRV	output	Gate-driver output for the external P-channel MOSFET switch. VCC-V_DRV swings ~6.3V low / 60mV high; rise/fall ~40ns into 2nF gate load.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn3763.step`	147 KB	You want the bare part, or you mark your own boards.
`cn3763-etched.step`	1.7 MB	You want the part with `CN3763` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 412 faces against 177 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.
