iCM(创芯微) · Battery Management · DFN-6L(1.6x1.9)

CM1003-CPD from iCM(创芯微), in a DFN-6L(1.6x1.9). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; leave unconnected.
2 CO output Charge MOSFET control terminal: CO goes high in normal operation and switches low to turn off charging on overcharge (delay TOC 1000 ms typ) or charge overcurrent (VCHA -0.060 V typ, delay TCHA 16 ms typ).
3 DO output Discharge MOSFET control terminal: DO goes high in normal operation and switches low to turn off discharging on overdischarge (VOD 2.500 V typ, delay TOD 64 ms typ), discharge overcurrent (VEC 0.060 V typ, delay TEC 16 ms typ) or load short circuit (VSHORT 0.165 V typ, delay TSHORT 280 µs typ).
4 VSS power_in Power ground, connected to the negative terminal of the supply (battery); the reference for all detection thresholds.
5 VDD power_in Power supply input, connected to the positive terminal of the supply (battery); the absolute maximum VDD to VSS voltage is VSS-0.3 V to VSS+8.0 V.
6 VM input Charge/discharge current sense terminal, connected to the negative terminal of the charger or load; absolute voltage range is VDD-28 V to VDD+0.3 V.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • 3D model: DFN-6L(1.6x1.9), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: cm1003-cpd-etched.step / cm1003-cpd-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cm1003-cpd.step / cm1003-cpd.glb are the bare package body.
