ME4075AM5G

MICRONE · Battery Management · SOT-23-5

ME4075AM5G 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 indicator output. Pulls low during charging (strong pull-down) and goes high-impedance when charging is complete or otherwise terminated. When driving a status LED, a 1k-10k series current-limit resistor must be used; tie to GND if the status indicator is unused.
2 GND power_in Device ground. Return path for all internal circuitry and the charge current from BAT.
3 BAT power_out Charge current output to the battery positive terminal. In constant-current mode IBAT = 1000 / RPROG. Regulated to VFLOAT = 3.6V in constant-voltage mode. Absolute max rating -0.3 to 6.5V, max continuous current 800mA.
4 VCC power_in Supply input, typically from a USB port or 4.5-6.5V adapter. Recommended operating range 4.0-6.5V (typ 5.0V). UVLO threshold ~3.7V. Absolute max -0.3 to 6.5V.
5 PROG passive Charge current programming pin. Connect an RPROG resistor from PROG to GND to set the constant-current charge level: IBAT = 1000 × VPROG / RPROG, with VPROG = 1V in CC mode (e.g. 2kΩ → 500mA, 1.25kΩ → 800mA). Floating this pin puts the device into shutdown mode.

Two STEP files. Same geometry, different body top:

File Size Use it when
me4075am5g.step 85 KB You want the bare part, or you mark your own boards.
me4075am5g-etched.step 1.7 MB You want the part with ME4075AM5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 429 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 (13 pp, sha256 6c0deed7f4a86285, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
