CM1003-CPD
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). |
