ME4074BM5G

MICRONE · Battery Management · SOT-23-5

ME4074BM5G 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. Strong pull-down while charging, high-impedance when charge terminates or the part is shut down. Drive an LED to VCC through a 1 k-10 kΩ series resistor; tie to GND if the indicator is not needed. Absolute max −0.3 V to 6.5 V; VOL ≈ 0.3 V at 5 mA sink.
2 GND power_in Device ground return. Should tie to a wide PCB copper pour to act as the primary thermal path from the SOT-23-5 lead frame.
3 BAT power_out Charge current output to the Li-Ion cell. In CC mode IBAT = 1000 V / RPROG (up to 800 mA). Also senses the battery voltage for the 4.2 V float regulation, 2.9 V trickle threshold and 4.05 V auto-recharge threshold. Absolute max −0.3 V to 6.5 V, 800 mA continuous.
4 VCC power_in Positive supply input from USB or AC adapter. Operating range 4.0 V - 6.5 V (5.0 V typ.); UVLO ≈ 3.7 V. Bypass with ≥1 µF; add ~1.5 Ω series with X5R ceramics to damp start-up transients. Absolute max −0.3 V to 6.5 V.
5 PROG bidirectional Charge-current program pin. Connect RPROG from PROG to GND: ICHG = 1000 V / RPROG (e.g. 2 kΩ → 500 mA, 1.25 kΩ → 800 mA). Servos to VPROG = 1.0 V in CC mode; monitor VPROG to read back IBAT = 1000·VPROG/RPROG. Floating PROG puts the device into shutdown (IBAT ≤ 2 µA, ICC ≈ 55 µA). Absolute max −0.3 V to VCC+0.3 V.

Provenance

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

  • Datasheet: MICRONE datasheet (None pp, sha256 c0eb3f3e35c88615, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
