A current sensing module (100) includes a shunt resistor (10) for receiving and sensing a current (Ib), a digital sensing circuit (20), and an analog sensing circuit (30) . The shunt resistor (10) includes a connecting part (10C), a first resistive part (10A) and a second resistive part (10B) coupled in series to the first resistive part (10A) via the connecting part (10C). The digital sensing circuit (20) measures a first analog voltage (V1) of the first resistive part (10A) when the current (Ib) flows through the first resistive part (10A), and provides a first digital measuring value (I1d) associated with the first analog voltage (V1). The analog sensing circuit (30) measures a second analog voltage (V2) of the second resistive part (10B) when the current (Ib) flows through the second resistive part (10B), and provides a second analog measuring value (V2a) associated with the second analog voltage (V2).
