FH7071GZ from 鑫飞宏, 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; DO inverts to switch off the discharge MOSFET on over-discharge, discharge over-current or short-circuit detection. |
| 2 | VM | input | Charge/discharge current detection terminal; VM must stay within VCC-12 V to VCC+0.3 V (absolute maximum), and the over-current thresholds are measured on this pin. |
| 3 | CO | output | Charge MOSFET control terminal; CO inverts to switch off the charge MOSFET on over-charge or charge over-current detection. |
| 4 | NC | unconnected | Not connected. |
| 5 | VCC | power_in | Power input connected to the positive terminal of the battery; the supply range is 1.0 V to 5.5 V (absolute maximum -0.3 V to 6 V). |
| 6 | VSS | power_in | Power ground connected to the negative terminal of the battery. |
