FH8261G3M from XIN FEI HONG, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DO | output | Discharge MOSFET control terminal; output turns off the discharge MOSFET on over-discharge, discharge overcurrent or short circuit. |
| 2 | VM | input | Charge/discharge current detection terminal, connected to the negative of the charger or load; absolute maximum input voltage VCC-15 to VCC+0.3 V. |
| 3 | CO | output | Charge MOSFET control terminal; output turns off the charge MOSFET on overcharge or charge overcurrent. |
| 4 | NC | unconnected | No connection. |
| 5 | VCC | power_in | Power supply input, connected to the positive terminal of the battery; operating range 1.5 to 6.0 V, absolute maximum -0.3 to 6.0 V. |
| 6 | VSS | power_in | Power supply ground, connected to the negative terminal of the battery. |
