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 (active-low, CHRG#). Pulled low by an internal switch while the battery is being charged; high-impedance when charging is terminated. Absolute maximum pin voltage 10 V; typical VOL = 0.3 V at I_CHRG = 5 mA. |+| 2 | GND | power_in | Device ground reference. |+| 3 | BAT | power_out | Battery connection pin. Connect the positive terminal of the single-cell Li-ion battery to this pin. Sources charge current and regulates the cell to 4.2 V ±1%. Drain current drops below 2 µA in disable/sleep mode. Absolute maximum 7 V; maximum sourcing current 800 mA. |+| 4 | VCC | power_in | Positive input supply voltage (typ. 5 V, range 4.0-8.0 V; absolute max 8 V). Powers the internal circuitry and pass PMOSFET. When VCC drops within 80 mV of the BAT pin voltage, the ME4064A enters low-power sleep, reducing I_BAT to <2 µA. UVLO threshold 3.7 V typ. |+| 5 | PROG | input | Constant charge-current setting and charge-current monitor pin. A resistor R_PROG from PROG to GND sets I_BAT via I_BAT = (V_PROG / R_PROG) × 1100. Regulated to 1.0 V in constant-current mode and 0.1 V in precharge mode; can also be used to monitor charge current. Absolute max voltage VCC+0.3 V; max current 1200 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `ME4064AM5G-NM5G`+- `ME4064AM5G-NAM5G-N`++## CAD (KiCad official)++- Symbol: `ME4064AM5G-N`+- 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/me4064am5g-n-datasheet.pdf) (16 pp, sha256 `2ffde19a7828fa2e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
