FH7071B from XIN FEI HONG, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DOUT | output | Discharge control output connected to gate of external discharge control N-MOS transistor Q2. |
| 2 | VM | input | Charge/discharge current detection input, connected through 1kΩ resistor to source of N-MOS transistor Q1, detects voltage drop across charge/discharge MOSFETs. |
| 3 | COUT | output | Charge control output connected to gate of external charge control N-MOS transistor Q1. |
| 4 | NC | unconnected | Not connected (floating pin). |
| 5 | VDD | power_in | Power supply input connected to positive terminal of battery, requires 0.1μF ceramic capacitor decoupling, operating voltage range -0.3V to +10V. |
| 6 | VSS | power_in | Power supply ground connected to negative terminal of battery. |
