ABSTRACT:
A power supply system includes load circuits connected to a power source circuit through respective power lines. Each of the power lines is provided with a breaker element such as a FET that connects and disconnects the power line to and from the load circuit, and an overcurrent detection resistor for detecting an overcurrent in the load circuit. If an overcurrent is detected according to a signal from the overcurrent detection resistor, a short-circuit protection controller opens the breaker element to cut off the power line from the load circuit. A voltage monitor circuit monitors the voltage of the load circuit, and a control circuit controls the load circuit.
