# FH7071DZ

**鑫飞宏** · Battery Management · SOT-23-6

FH7071DZ 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; the datasheet gives no numeric limit for this pin, and it drives the discharge-control MOSFET off during overdischarge, overcurrent, or short-circuit states. |
| 2 | VM | input | Charge/discharge current sense terminal; VM input voltage is rated VCC-12 V to VCC+0.3 V (absolute maximum), and the IC compares it against the charge overcurrent (VCHA) and discharge overcurrent/short-circuit (VEC, VSHORT) thresholds. |
| 3 | CO | output | Charge MOSFET control terminal; the datasheet gives no numeric limit for this pin, and it turns the charge-control MOSFET off during overcharge or charge overcurrent states. |
| 4 | NC | unconnected | Not connected (no internal connection stated in the datasheet). |
| 5 | VCC | power_in | Power supply input connected to the positive terminal of the battery; supply voltage is rated -0.3 V to 6 V absolute maximum, with 1.0 V to 5.5 V operating range. |
| 6 | VSS | power_in | Power ground connected to the negative terminal of the battery; it is the reference for VCC and VM measurements. |
