ME4064AM5G-N 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 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.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me4064am5g-n.step`	85 KB	You want the bare part, or you mark your own boards.
`me4064am5g-n-etched.step`	1.9 MB	You want the part with `ME4064AM5G-N` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 493 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.
