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 | TEMP | input | Battery temperature sense input. Connect to an external NTC thermistor divider to monitor battery temperature; charging is suspended when V(TEMP) is below 45%*VCC or above 80%*VCC (over/under temperature). Tie directly to GND if temperature monitoring is not used. |+| 2 | PROG | passive | Constant-current program and charge-current monitor pin. An external resistor R_PROG from PROG to GND sets the fast-charge current per I_BAT = (V_PROG / R_PROG) * 1100, with V_PROG ≈ 1.0V. Typical values: R_PROG = 1.1kΩ → 1000mA, 2.2kΩ → 500mA. |+| 3 | GND | power_in | Device ground reference. The exposed thermal PAD on the ESOP-8 package should also be soldered to the GND plane to improve thermal dissipation for the internal pass MOSFET. |+| 4 | VCC | power_in | Chip input supply pin, typically from a USB port or AC adapter. Operating range 4.0V to 9.0V (absolute max 10V); when VCC drops to within ~80mV of V(BAT) the chip shuts down and enters sleep mode (leakage < 2µA). |+| 5 | BAT | power_out | Battery connection / charge current output. Regulated float voltage is 4.2V (ME4057ASPG-N) with ±1% accuracy; supplies up to 1A programmed charge current to a single Li-ion/Li-polymer cell. |+| 6 | STDBY | output | Open-drain charge-complete (standby) status indicator, active low. Internal N-channel pulls STDBY low when charging has terminated (charge current below C/10); high-impedance otherwise. |+| 7 | CHRG | output | Open-drain charge status indicator, active low. Internal N-channel pulls CHRG low while a charge cycle is in progress; high-impedance in all other states. |+| 8 | CE | input | Chip enable input. Drive high to enable normal charger operation, drive low to shut the chip down. Compatible with TTL or CMOS logic levels; absolute max 10V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ME4057ASPG-N`+- `ME4057ASPG-NDSPG-N`++## CAD (KiCad official)++- Symbol: `ME4057ASPG-N`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me4057aspg-n-datasheet.pdf) (17 pp, sha256 `3b33536d2bdfda15`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
