Abstract: A signal transmission circuit is formed by a transmitter, a receiver, a transmission line therebetween, and a bias circuit. The transmitter receives an input signal to transmit a signal corresponding to the input signal to the input of the transmission line. A voltage amplitude of the transmitted signal is smaller than a voltage amplitude defined by first and second power supply terminals. The receiver receives the transmitted signal, adjusts a voltage of the received signal in accordance with a bias voltage to generate a voltage adjusted signal, and wave-shapes the voltage adjusted signal to generate an output signal. The bias circuit differentially amplifies the output signal of the receiver and an inverted signal thereof to generate the bias voltage.

Abstract: An overcurrent sensing circuit for sensing an overcurrent flowing through a power MOS transistor is described. A voltage drop equal to the voltage across the drain and source of a power MOS transistor that changes due to change in a load current is generated in a sensing resistor that is connected between the source of a sensing MOS transistor having its gate and drain connected in common with those of the power MOS transistor and the source of the power MOS transistor due to current that flows through the sensing MOS transistor. This voltage is inputted to a comparator that has an added offset voltage, and the comparator judges that the power MOS transistor is in an overcurrent condition when this inputted voltage exceeds an input offset voltage value that is set inside the comparator.
