iCM(创芯微) · IC · DFN-6L(1.6x1.9)

CM1003-DHD 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 connection; the datasheet lists this pin as not connected (无连接).
2 CO output Charge MOSFET control terminal; CO voltage is limited to VVM-0.3 V to VDD+0.3 V (absolute maximum ratings).
3 DO output Discharge MOSFET control terminal; DO voltage is limited to VSS-0.3 V to VDD+0.3 V (absolute maximum ratings).
4 VSS power_in Power ground, connected to the negative terminal of the supply battery; VDD to VSS absolute maximum range is VSS-0.3 V to VSS+8.0 V.
5 VDD power_in Power supply input connected to the battery positive terminal; VDD to VSS absolute maximum range is VSS-0.3 V to VSS+8.0 V.
6 VM input Charge/discharge current sense terminal connected to the negative side of the charger or load; VM voltage is limited to VDD-28 V to VDD+0.3 V (absolute maximum ratings).
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: CM1003-DHD
  • Footprint: Package_DFN_QFN:DFN-6-1EP_2x1.6mm_P0.5mm_EP1.15x1.3mm
  • 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-dhd-etched.step / cm1003-dhd-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cm1003-dhd.step / cm1003-dhd.glb are the bare package body.
