摘要： A current sensing module includes a shunt resistor for receiving and sensing a current, a digital sensing circuit, and an analog sensing circuit. The shunt resistor includes a connecting part, a first resistive part and a second resistive part coupled in series to the first resistive part via the connecting part. The digital sensing circuit is coupled to the first resistive part for measuring a first analog voltage of the first resistive part when the current flows through the first resistive part, and providing a first digital measuring value associated with the first analog voltage. The analog sensing circuit is coupled to the second resistive part for measuring a second analog voltage of the second resistive part when the current flows through the second resistive part, and providing a second analog measuring value associated with the second analog voltage.
