FM2113

Shenzhen Fuman · Battery Management · SOT-23-6

FM2113 from Shenzhen Fuman, in a SOT-23-6. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OD output Discharge control output. Connects to the gate of the external discharge control N-MOSFET (Q2). Drives high (VDD-0.02 V typ) in normal state and low (0.1 V typ) during over-discharge, over-current, or short-circuit protection.
2 CS input Discharge current sense input. Connects to the source/drain node of the external charge-control N-MOSFET (Q1) via a series resistor (typ 2 kΩ). Senses voltage drop across Q1+Q2 for over-current (VDIP ≈ 150 mV) and short-circuit (VSIP ≈ 1.0 V) detection. Absolute max rating VDD-20 V to VDD+0.3 V.
3 OC output Charge control output. Connects to the gate of the external charge control N-MOSFET (Q1). Drives high (VDD-0.02 V typ) in normal state and low (0.1 V typ) during over-charge or charge-over-current protection. Absolute max rating VDD-20 V to VDD+0.3 V.
4 NC unconnected Not connected. Leave floating or tie per PCB layout convention.
5 VDD power_in Power supply input. Connect to the positive terminal of the battery through a 100 Ω series resistor (R1). A 0.1 µF ceramic decoupling capacitor is required between VDD and VSS. Operating range 1.5 V to 8 V (absolute max VSS-0.3 to VSS+10 V). Operating current 3.0 µA typ at VDD=3.9 V.
6 VSS power_in Ground / negative supply. Connect to the negative terminal of the battery cell.

CAD (KiCad official)

  • Symbol: FM2113
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: fm2113-etched.step / fm2113-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fm2113.step / fm2113.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
fm2113.step 97 KB You want the bare part, or you mark your own boards.
fm2113-etched.step 1.2 MB You want the part with FM2113 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 311 faces against 117 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: Shenzhen Fuman datasheet (8 pp, sha256 60016c51cced1a1c, 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).
