ME4084AM5G

MICRONE · Battery Management · SOT-23-5

ME4084AM5G 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. Pulled low by an internal switch while the battery is being charged; high-impedance otherwise. Typical output low voltage 0.3V at I_CHRG=5mA (max 0.6V). Absolute max pin voltage 24V.
2 GND power_in Device ground / power return.
3 BAT power_out Battery connection pin. Connect the positive terminal of the single-cell Li-ion battery here. Provides charge current to the battery and regulates to 4.2V float voltage. Absolute max pin voltage 16V; absolute max continuous current 1200mA.
4 VCC power_in Positive input supply voltage. Operating range 4.7V-6.5V (typ. 5V); absolute max 24V with -0.3V minimum. Over-voltage protection trips at ~6.5V. When VCC drops within ~70mV of the BAT pin voltage the device enters low-power sleep mode, dropping I_BAT to <1µA.
5 PROG passive Constant charge current setting and charge current monitor pin. Set the constant-current charge level by connecting a resistor R_PROG from PROG to GND (I_BAT = 930 / R_PROG). Typical V_PROG ≈ 1.0V in current-regulation mode. For 600mA charge (ME4084AM5G) use R_PROG=1.53kΩ. Absolute max PROG voltage 6V, max pin current 1200µA.

CAD (KiCad official)

  • Symbol: ME4084AM5G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: me4084am5g-etched.step / me4084am5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me4084am5g.step / me4084am5g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me4084am5g.step 85 KB You want the bare part, or you mark your own boards.
me4084am5g-etched.step 1.8 MB You want the part with ME4084AM5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 466 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: MICRONE datasheet (20 pp, sha256 64c9ce3e0f9cce37, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
