Abstract
A load detection device includes a signal output circuit, comparison circuit, sensing circuit, detection circuit, logic circuit, and control circuit. The signal output circuit outputs a forced current, and generates a bias signal, a first output signal, a second output signal, and a feedback signal depending on the forced current. The comparison circuit compares the reference signal output with the first and second output signals to generate an accurate comparison output for indicating the load state. The sensing circuit generates a sensing signal according to the feedback signal. The detection circuit generates a rough detection output for indicating the load state according to the sensing signal and the first and second output signals. The logic circuit obtains the load state according to the precise comparison output and the rough detection output. The control circuit enables the signal output circuit, comparison circuit, sensing circuit, and logic circuit.
