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.
