FH8261G3M

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

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.
