ME4075AM5G from MICRONE, in a SOT-23-5. 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 | CHRG | output | Open-drain charge status indicator output. Pulls low during charging (strong pull-down) and goes high-impedance when charging is complete or otherwise terminated. When driving a status LED, a 1k-10k series current-limit resistor must be used; tie to GND if the status indicator is unused. |
| 2 | GND | power_in | Device ground. Return path for all internal circuitry and the charge current from BAT. |
| 3 | BAT | power_out | Charge current output to the battery positive terminal. In constant-current mode IBAT = 1000 / RPROG. Regulated to VFLOAT = 3.6V in constant-voltage mode. Absolute max rating -0.3 to 6.5V, max continuous current 800mA. |
| 4 | VCC | power_in | Supply input, typically from a USB port or 4.5-6.5V adapter. Recommended operating range 4.0-6.5V (typ 5.0V). UVLO threshold ~3.7V. Absolute max -0.3 to 6.5V. |
| 5 | PROG | passive | Charge current programming pin. Connect an RPROG resistor from PROG to GND to set the constant-current charge level: IBAT = 1000 × VPROG / RPROG, with VPROG = 1V in CC mode (e.g. 2kΩ → 500mA, 1.25kΩ → 800mA). Floating this pin puts the device into shutdown mode. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 429 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
