FH7071HZ 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, held high in normal operation and switched low to turn off discharging on over-discharge, discharge overcurrent or short circuit. |
| 2 | VM | input | Charge/discharge current sense terminal, where VM must stay between VCC-12 V and VCC+0.3 V and is compared against the charge overcurrent (-0.150 V), discharge overcurrent (0.180 V) and short-circuit (1.000 V) thresholds listed for FH7071HZ. |
| 3 | CO | output | Charge MOSFET control terminal, held high in normal operation and switched low to stop charging on over-charge or charge overcurrent detection. |
| 4 | NC | unconnected | Not connected; the datasheet states no internal function for this pin. |
| 5 | VCC | power_in | Power supply input connected to the battery positive terminal, with an operating supply range of 1.0 to 5.5 V and an absolute maximum of -0.3 to 6 V. |
| 6 | VSS | power_in | Power ground connected to the battery negative terminal and the reference for all voltage detection. |
