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.

3D model downloads

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.
