CN3152 from ShangHai Consonance Elec, in a ESOP-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	TEMP	input	Battery temperature sense input. Connect to the output of the battery pack NTC divider. Charging is suspended when the pin voltage is below 45% or above 80% of VIN (indicating over/under temperature). Tie to GND to disable temperature monitoring. Input current <0.5µA.
2	ISET	passive	Constant-current charge setpoint and charge-current monitor. Connect a resistor RISET from this pin to GND to program charge current: ICH = (VISET × 1011) / RISET. VISET = 1.205V in CC mode and 0.12V in precharge. End-of-charge threshold Vterm = 0.12V.
3	GND	power_in	Power ground.
4	VIN	power_in	Positive input supply, 3.8V to 6V (absolute max 6.5V). Powers the internal circuitry and the pass transistor. UVLO threshold ~3.2-3.8V. When VIN falls within 10mV of VBAT the chip enters sleep mode (IBAT <3µA).
5	BAT	power_out	Battery connection. Sources the regulated 4.2V (±1%) charging voltage and up to 1A charge current to the Li-ion/Li-poly cell. Sinks <3µA from the battery when disabled or in sleep mode. Recharge threshold VREG − 0.15V; precharge threshold 2.93V.
6	DONE	output	Charge-complete status indicator, open-drain (active-low, /DONE). Pulled low when the charge current drops below 10% of the programmed CC value, indicating end-of-charge; otherwise high-impedance. Sink capability 10mA at VDONE = 0.3V; leakage <1µA at 6V. Can be tied to GND if unused.
7	CHRG	output	Charging status indicator, open-drain (active-low, /CHRG). Pulled low while CN3152 is charging; high-impedance otherwise. Sink capability 10mA at VCHRG = 0.3V; leakage <1µA at 6V.
8	CE	input	Chip enable input. Logic high (VIH ≥2.2V) enables normal operation; logic low (VIL ≤0.7V) disables the chip (IBAT <3µA). TTL/CMOS compatible. Input current ±1µA.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn3152.step`	125 KB	You want the bare part, or you mark your own boards.
`cn3152-etched.step`	1.5 MB	You want the part with `CN3152` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 376 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.
