CN3302 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	STAT	output	Charge status indicator output (CMOS). High level indicates the charger is in charging state; low level indicates charging has ended. Can drive an LED directly or interface with an MCU input; sink/source capability ~10mA.
2	CE	input	Chip enable input. A high level (>=2.2V) enables normal operation; a low level (<=0.7V) shuts CN3302 down. Compatible with TTL/CMOS logic levels; do not leave floating between 0.7V and 2.2V.
3	BAT	input	Battery voltage feedback input. Connects directly to the positive terminal of the 2-cell Li-ion battery to sense pack voltage (charge termination 8.4V typ, recharge 8.095V typ, over-voltage protection ~1.0663 x Vterm). Absolute max -0.3V to 18V.
4	GND	power_in	Power ground / device return. Common ground for the input supply and the battery negative terminal.
5	LDRV	output	Gate driver output for the external low-side N-channel power MOSFET. Drives the switch that stores energy in the boost inductor; typical peak drive current ~0.65A, VOH >= VCC-0.3V, VOL <= 0.3V.
6	HDRV	output	Gate driver output for an optional external high-side P-channel power MOSFET. Used only when low-battery / short-circuit protection with buck-mode operation is needed; leave floating if not used. Typical peak drive current ~0.8A.
7	VIN	power_in	Positive supply input (2.75V to 6.5V) that powers the internal circuitry and also serves as the positive terminal of the inductor / input current sense. Quiescent current ~280 uA at VBAT=8.6V, no switching.
8	CSN	input	Inductor / input current sense negative input. A sense resistor Rcs is connected between VIN and CSN; in normal operation (VIN-CSN) has an upper threshold of ~125 mV and lower threshold of ~85 mV (constant-current mode).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn3302.step`	122 KB	You want the bare part, or you mark your own boards.
`cn3302-etched.step`	1.7 MB	You want the part with `CN3302` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 415 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.
