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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `ME4075AM5GAM5G`++## CAD (KiCad official)++- Symbol: `ME4075AM5G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me4075am5g-datasheet.pdf) (13 pp, sha256 `6c0deed7f4a86285`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
