FH2112CB from XIN FEI HONG, 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 | OD | output | Gate connection for the discharge control MOSFET; driven low on overdischarge, discharge overcurrent or load short (output high VDD-0.02V typ, low 0.1-0.5V). |
| 2 | CS | input | Overcurrent detection input and charger detection pin; high-voltage design with absolute maximum range VDD-20V to VDD+0.3V. |
| 3 | OC | output | Gate connection for the charge control MOSFET; driven low on overcharge or charge overcurrent, absolute maximum range VDD-20V to VDD+0.3V. |
| 4 | NC | unconnected | No connection. |
| 5 | VDD | power_in | Positive power supply input; operating voltage VDD-VSS 1.5V to 8V, absolute maximum VSS+10V. |
| 6 | VSS | power_in | Ground, negative power supply input (0V reference). |
