DW01A from PUOLOP, in a SOT-23-6L. 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	OD	output	Gate drive output for the discharge-control MOSFET. Output 'H' is VCC-0.2V typical (sourcing 10µA at VCC=3.9V); output 'L' is 0.2V typical (sinking 10µA at VCC=2V). Driven low to disable discharge during overdischarge or overcurrent events.
2	VM	input	Current-sense / charger-detect input. Monitors the voltage across the two series discharge/charge FETs to detect overcurrent (VEDI = 150mV typ) and short-circuit (Vshort = 1.36V typ) events, and to detect charger connection (V0CHA = 1.2V min). Absolute max VDD-24V to VDD+0.3V.
3	OC	output	Gate drive output for the charge-control MOSFET. Output 'H' is VCC-0.02V typical (sourcing 10µA at VCC=3.9V). Driven low (toward VM) to disable charging during overcharge events.
4	TD	input	Factory test pin used to reduce internal delay times for production testing. Leave unconnected (or tie per manufacturer application circuit) in normal operation.
5	VCC	power_in	Positive supply pin, connected to the cell's positive terminal through a series resistor R1 (typ 100Ω) with a 0.1µF bypass capacitor to GND. Absolute max VDD range −0.3V to +10V; typical operating voltage 1.8V to ~4.35V from a single Li-ion cell.
6	GND	power_in	Ground / VSS reference, tied to the cell's negative terminal (pack internal negative, upstream of the protection FETs).

3D model: SOT-23-6L (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`dw01a.step`	97 KB	You want the bare part, or you mark your own boards.
`dw01a-etched.step`	1.0 MB	You want the part with `DW01A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 271 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.
