**Shenzhen Fuman** · Battery Management ICs · SOT-23-6

9017S from Shenzhen Fuman, 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 | CHRG | output | Charge indicator pin (充电指示脚). |
| 2 | GND | power_in | Ground. |
| 3 | BAT | power_out | Charge current output to the battery, with a preset float voltage of 4.2V ±1.5% and absolute maximum of 7V. |
| 4 | VCC | power_in | Power supply input, 4.25V to 6.5V operating range with 7V absolute maximum. |
| 5 | CHRGT | output | Charge-complete indicator pin (充电完成指示脚). |
| 6 | PROG | passive | Charge current programming and monitoring pin: an external resistor to ground sets the current, with the pin held at 0.1V in precharge and 1V in constant-current charge. |
