FHDW01A

XIN FEI HONG · Battery Management · SOT-23-6

FHDW01A from XIN FEI HONG, 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 of the external discharge-control N-MOSFET Q2. High (=VDD) in normal state to turn Q2 on; pulled to VSS to disable discharge on overdischarge/overcurrent/short-circuit protection.
2 VM input Charge/discharge current sense input. Connects through a current-limit resistor (typ. 1kΩ, R2) to the source of the external charge-control N-MOSFET Q1, sensing the voltage drop across Q1+Q2 to detect discharge overcurrent, short-circuit and charger presence (VCHG typ. -0.5V, VEDI typ. 0.150V, VSHORT typ. 1.260V vs VSS).
3 COUT output Charge control output. Connects to the gate of the external charge-control N-MOSFET Q1. High (=VDD) in normal state to turn Q1 on; pulled to VM to disable charging on overcharge protection.
4 NC unconnected No connect. Leave floating (悬空).
5 VDD power_in Positive supply / battery-sense input. Connects to the battery positive terminal through R1 (typ. 100Ω) and should be decoupled with a 0.1µF ceramic capacitor to VSS. Operating range 1.5V-10V; absolute max -0.3V to +10V.
6 VSS power_in Ground / negative supply. Connects to the battery negative terminal. All threshold voltages in the datasheet are referenced to VSS.

CAD (KiCad official)

  • Symbol: FHDW01A
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: fhdw01a-etched.step / fhdw01a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fhdw01a.step / fhdw01a.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
fhdw01a.step 97 KB You want the bare part, or you mark your own boards.
fhdw01a-etched.step 1.2 MB You want the part with FHDW01A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 317 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

  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
