    摘要: An improved circuit for controlling the maximum current in a MOS power transistor, in which resistor is in series with the drain-source path of the MOS power transistor. The supply terminal of a transconductance operational amplifier is connected to the output of a voltage-raising or charge pump circuit which can output a voltage higher than that of the voltage supply to which the drain of the MOS transistor is connected. The inputs of the amplifier are connected to the resistor and its output is connected to the gate of the MOS transistor so that, in operation, the maximum current flowing through the power transistor is limited to a value proportional to a reference voltage.

    摘要: A power-on reset circuit, which may be utilized with CMOS integrated circuits, includes first and second series-connected inverters, wherein the output of the second inverter provides a reset signal. A series of switches and a biasing line having two series-connected diodes are integrally arranged with the inverters. Capacitive coupling to ground and the supply voltage is employed to prevent any static current path between supply voltage rails. The circuit provides a short duration reset signal which follows the supply voltage and is insensitive both to rebound signals on the supply voltage rails and to internal and external noise.

    摘要: The amplitude of the hysteresis of the circuit is determined principally by the intensity of the current produced by a generator by means of a "band gap" reference voltage, an internal resistance of the circuit, and the resistances connected to the emitters of the input-stage transistors, enabling a high degree of precision to be achieved. The inputs of the circuit are defined by the bases of the input-stage transistors and therefore have high impedance. The preferred application is for forming interface circuits for sensors to be fitted in motor vehicles.
