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 output. Pulled low by an internal switch while the battery is being charged; high-impedance when not charging. VCHRG typ 0.3V @ 5mA sink. Absolute max -0.3 to 6.5V. |+| 2 | GND | power_in | Ground reference for the device. |+| 3 | BAT | power_out | Battery connection pin. Connect to the positive terminal of the Li-Ion cell. Sources up to 800mA of charge current and regulates the float voltage to 4.2V. Battery drain current drops to <2µA when the IC is in disable or sleep mode. Abs max -0.3 to 6.5V, 800mA. |+| 4 | VCC | power_in | Positive input supply voltage (4.0V min, 5.0V typ, 6.5V max). Provides power to the internal circuit. When VCC drops within 80mV of BAT, the ME4055A enters low-power sleep mode, dropping IBAT to <2µA. Bypass with ≥1µF to GND. |+| 5 | STDBY | output | Open-drain charge-terminated status output. Pulled low by an internal switch to indicate the battery charge cycle has terminated; otherwise high-impedance. Abs max -0.3 to 6.5V. |+| 6 | PROG | bidirectional | Constant charge-current setting and charge-current monitor pin. Charge current is programmed by a resistor RPROG from PROG to GND (IBAT = 1100 × VPROG / RPROG). Regulates to 1V in constant-current mode and 0.1V in precharge mode; PROG voltage also serves as a monitor of instantaneous charge current. Abs max -0.3 to VCC+0.3V, 1200µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `ME4055AM6G`++## CAD (KiCad official)++- Symbol: `ME4055AM6G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me4055am6g-datasheet.pdf) (17 pp, sha256 `6cd295b8ef426213`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
