Abstract
A real-time load current detecting circuit composed of a power supply circuit, a delay circuit, a current sensing circuit, and a current feedback circuit. The power supply circuit is adapted for providing the CPU with a power source. The delay circuit includes a resistor and a capacitor, connected to the power supply circuit. The current sensing circuit includes a comparison circuit connected to the delay and power supply circuits. The current feedback circuit includes a feedback current source and a resistor, connected to the current sensing circuit. The feedback current source is adapted for mirroring a current sensed by the current sensing circuit. In light of this, the current can be accurately monitored and detected and there is hardly inaccuracy for the detection of the current.
