CM1003-Z from iCM(创芯微), in a SOT-23-6. 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 DO output Discharge MOSFET control terminal that drives the discharge-control MOSFET; the datasheet's absolute maximum DO output voltage is VSS-0.3 V to VDD+0.3 V.
2 VM input Charge/discharge current sense terminal, connected to the negative terminal of the charger or load; the datasheet's absolute maximum VM input voltage is VDD-28 V to VDD+0.3 V.
3 CO output Charge MOSFET control terminal that drives the charge-control MOSFET; the datasheet's absolute maximum CO output voltage is VVM-0.3 V to VDD+0.3 V.
4 NC unconnected No connection.
5 VDD power_in Power supply input connected to the positive terminal of the battery; the datasheet's absolute maximum VDD-to-VSS input voltage is VSS-0.3 V to VSS+8.0 V.
6 VSS power_in Power ground connected to the negative terminal of the battery.
