CM1003-BHS

iCM(创芯微) · IC · SOT-23-6

CM1003-BHS 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 output that switches the discharge MOSFET off during over-discharge, discharge over-current, and load short-circuit; its absolute maximum voltage range is VSS-0.3 V to VDD+0.3 V.
2 VM input Charge/discharge current detection terminal connected to the negative terminal of the charger or load, with an absolute maximum input voltage range of VDD-28 V to VDD+0.3 V.
3 CO output Charge MOSFET control output that switches the charge MOSFET off during over-charge and charge over-current; its absolute maximum output voltage range 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 supply (battery); VDD to VSS absolute maximum range is VSS-0.3 V to VSS+8.0 V.
6 VSS power_in Power ground terminal connected to the negative terminal of the supply (battery).
