DW01-A

Shenzhen Fuman · Battery Management · SOT-23-6

DW01-A from Shenzhen Fuman, 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 DOUT output Discharge control output. Connects to the gate (G) of the external discharge-control N-MOSFET Q2. High = Q2 on (discharge enabled); low (VSS level) = Q2 off (discharge cut off) under over-discharge or over-current fault.
2 VM input Charge/discharge current sense input. Connects through a current-limit resistor (typ. 1 kΩ) to the source of the charge-control N-MOSFET Q1, sensing the voltage drop across Q1+Q2. Used to detect charger presence (VCHG ≈ -0.5 V), over-current discharge (VEDI ≈ 0.15 V), and battery short (VSHORT ≈ 1.36 V).
3 COUT output Charge control output. Connects to the gate (G) of the external charge-control N-MOSFET Q1. High = Q1 on (charge enabled); low (VM level) = Q1 off (charge cut off) under over-charge fault.
4 NC unconnected No connect. Leave floating.
5 VDD power_in Positive supply input, connected to the battery positive terminal through a series resistor R1 (typ. 1 kΩ). Absolute max -0.3 V to +10 V; operating 1.5 V to 10 V. Requires a 0.1 µF ceramic decoupling cap to VSS. Typical supply current 2 µA (VDD = 3.9 V), 0.7 µA in low-power mode.
6 VSS power_in Ground / negative supply. Connects to the battery negative terminal. All internal thresholds are referenced to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
dw01-a.step 97 KB You want the bare part, or you mark your own boards.
dw01-a-etched.step 1.1 MB You want the part with DW01-A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 280 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Shenzhen Fuman datasheet (10 pp, sha256 6fcfde09264c5e11, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
