ME4054BM5G-N

MICRONE · Battery Management · SOT-23-5

ME4054BM5G-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. Pulled low by an internal N-channel switch while a charge cycle is in progress; high-impedance otherwise (VOL ≈ 0.3 V at ICHRG = 5 mA, max 0.6 V). Absolute max pin voltage 6.5 V. Tie through an LED+resistor (typ 1 kΩ) to VCC or leave with a pull-up.
2 GND power_in Device ground. Return for VCC, BAT, and PROG. Must be tied to the PCB ground plane; also serves as the primary thermal path for the SOT-23-5.
3 BAT power_out Battery connection pin. Sources up to 500 mA of charge current to the single-cell Li-Ion cell and regulates the float voltage to 4.2 V ±1%. In shutdown/sleep mode BAT sink current drops to <2 µA. Absolute max voltage −0.3 to 6.5 V; absolute max current 500 mA.
4 VCC power_in Positive input supply (typ 5 V, operating 4.0-6.5 V; recommended ≤5.5 V at 0.5 A charge). Powers all internal circuitry and the pass MOSFET. When VCC drops within ~80 mV of VBAT (VASD), the device enters low-power sleep mode (IBAT < 2 µA). Bypass with a 1 µF capacitor to GND.
5 PROG passive Charge-current program and monitor pin. A resistor RPROG from PROG to GND sets the constant-current charge level: ICHG = 1000 V / RPROG (e.g. 2 kΩ → 500 mA, 10 kΩ → 100 mA). Regulated to 1 V in CC mode and 0.1 V in precharge; measuring VPROG gives IBAT = 1000·VPROG/RPROG. Leaving PROG floating puts the chip into disable/shutdown mode. Absolute max −0.3 V to VCC+0.3 V, 800 µA.

Ordering variants

Same part, different packaging or reel option.

  • ME4054BM5G-N

CAD (KiCad official)

  • Symbol: ME4054BM5G-N
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: me4054bm5g-n-etched.step / me4054bm5g-n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me4054bm5g-n.step / me4054bm5g-n.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me4054bm5g-n.step 85 KB You want the bare part, or you mark your own boards.
me4054bm5g-n-etched.step 2.0 MB You want the part with ME4054BM5G-N already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 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.
