DW06 from JSMSEMI, in a SOT-23-6. 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	V-	input	Current-sense input pin and charger-detection input. Monitors the voltage between BATT- and GND to detect overcurrent, short-circuit and charger-present conditions (VCHA ≈ -0.5 V; VOI1 ≈ 150 mV; VOI2 ≈ 1.0 V).
2	S1	passive	Source of the internal charge-control MOSFET; connects to the charging negative terminal (pack B-/BATT- node through the sense resistor path).
3	S2	passive	Source of the internal discharge-control MOSFET; tied externally to VSS (cell negative) per the typical application.
4	D	passive	Common drain node of the internal charge and discharge MOSFETs (back-to-back FET common-drain connection). Left as an internal-only pin in typical applications.
5	VDD	power_in	Positive supply input, connects to the Li-ion cell positive terminal through a series resistor (typ. 100 Ω) with a decoupling cap (typ. 0.1 uF) to VSS. Operating range 1.5 V to 10 V; absolute max VSS+12 V.
6	VSS	power_in	Ground / negative supply; connects to the Li-ion cell negative terminal and is the reference for all internal detection thresholds.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`dw06.step`	97 KB	You want the bare part, or you mark your own boards.
`dw06-etched.step`	1.1 MB	You want the part with `DW06` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 272 faces against 117 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.
