FH9261-G3M

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

FH9261-G3M 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 OD output Discharge control MOSFET gate drive output. Drives the gate of the external N-MOSFET that controls the discharge path. Goes low (VDL ~0.1V) when overdischarge, discharge overcurrent, or load short-circuit is detected; otherwise high (VDH ~ VDD-0.02V).
2 CS input Overcurrent detection input / charger detection terminal. Senses the voltage across the series MOSFETs (Rds(on)) for discharge overcurrent (VDIP=100mV), charge overcurrent (VCIP=-100mV), and load short-circuit (VSIP≈0.58V) protection. Absolute max: VDD-25 V to VDD+0.3 V.
3 OC output Charge control MOSFET gate drive output. Drives the gate of the external N-MOSFET that controls the charge path. Goes low (VCL ~0.1V) when overcharge or charge overcurrent is detected; otherwise high (VCH ~ VDD-0.02V). High-voltage tolerant (absolute max VDD-25V to VDD+0.3V) for reverse-charger protection.
4 NC unconnected No connection. Leave floating on the PCB.
5 VDD power_in Positive power supply input; connects to the battery positive terminal through a series resistor R1 (typ. 100Ω) with a 0.1µF bypass capacitor to VSS. Operating range VDD-VSS = 1.5V to 8V. Absolute max VSS-0.3 V to VSS+10 V. Operating current typ. 3.0 µA at VDD=3.9V.
6 VSS power_in Ground / negative power supply input. Connects to the battery negative terminal.

CAD (KiCad official)

  • Symbol: FH9261-G3M
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: fh9261-g3m-etched.step / fh9261-g3m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fh9261-g3m.step / fh9261-g3m.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
fh9261-g3m.step 97 KB You want the bare part, or you mark your own boards.
fh9261-g3m-etched.step 1.9 MB You want the part with FH9261-G3M already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 472 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: XIN FEI HONG datasheet (18 pp, sha256 3215be66c4cfc32f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
