    摘要: A supply current is supplied to an error detection circuit for detecting an error condition of an IC of the power supply circuit such as an overheat detection circuit only when the detection current of the power transistor of the power supply circuit is higher than a reference. Moreover, a supply current to the constant current source is supplied only when the detection current of the power transistor is higher than the reference to suppress the power consumption. Thus, suppression of the power consumption in the battery backup operation for a RAM during ignition off condition is provided. The current detection of the power transistor of the power supply circuit is detected with a series resistor or a multi-collector transistor.

    摘要: A method and apparatus provide for improved crowbar protection in a shunt regulator circuit including a shunt device. An over-temperature protection circuit may be combined with a fast-crowbar protection circuit such that maximum protection from damaging thermal energy is provided to a shunt device. The fast-crowbar protection circuit estimates the thermal energy in the shunt device based upon an integration method. By integrating a measured power over time the rise in temperature can be estimated such that the crowbar protection is enabled before the thermal energy can damage the shunt device. The integration method can be approximated using a piece-wise linear approximation such that the estimation circuitry can be simplified. A series of comparators and timing/delay circuits are employed to measure a current level in the shunt device over a given duration. The timing/delay circuits have memory such that heat build up and heat dissipation are modeled.

    摘要: The semiconductor component has a circuit configuration for driving an electrical load. The circuit includes a control circuit with a power switch driven by a drive configuration and feeding a current to the load. The semiconductor component has a first temperature detector thermally closely coupled to the power switch and a further temperature detector. A temperature evaluation circuit receives temperature signal from the temperature detectors and generates a signal that depends on the signals of the temperature detectors and feeds the signal to the drive configuration.

    摘要: A fuseless DC-DC converter is provided to protect a circuit from overcurrent without involvement of a protective fuse. This is accomplished by providing a load circuit in the converter that includes a first overheat self-interruption-type semiconductor switch in series between a DC power supply and a load, and a reference circuit including a second overheat self-interruption-type semiconductor switch in parrallel with the first switch, and a reference resistor with one end connected to the source of the second switch, and the other end grounded. Also included is a comparator circuit that compares the source voltage of the first switch with a reference voltage applied to the source of the second switch, and thereby determines if the circuit has overcurrent. If overcurrent is detected, the results from the comparator circuit are used by a power supply controller to deactivate the semiconductor switch.
