摘要： A field-effect-controllable power semiconductor component has a drain terminal, a source terminal, a gate terminal, a drain-to-source voltage and a load current. A circuit configuration for detecting the load current of the power semiconductor component includes a further field-effect-controllable semiconductor component through which a fraction of the load current flows. The further semiconductor component has a drain terminal connected to the drain terminal of the power semiconductor component, a gate terminal connected to the gate terminal of the power semiconductor component, a source terminal and a drain-to-source voltage. A resistor at which a voltage proportional to the load current can be picked up, is connected to a fixed potential terminal. A controllable resistor is connected between the resistor and the source terminal of the further semiconductor component. The controllable resistor adjusts the current of the further semiconductor component so that the drain-to-source voltages of the power semiconductor component and the further semiconductor component are equal to one another.

摘要： The temperature of a power semiconductor component is monitored by feeding the block current of a bipolar transistor which is in thermal contact with the component to an amplifying current mirror. The output signal of the current mirror is compared with a reference current. If the mirrored current is greater than the reference current, then the system produces a corresponding output. Temperatures of the power semiconductor component below 140.degree. C. can be reliably detected.

摘要： Power FETs having a load at the source side require a gate voltage lying above the drain voltage in order to be driven completely conductive. This can occur with a known pump circuit. In the drive circuit disclosed, the diode connected to the gate terminal of the power FET is a depletion FET whose substrate terminal is applied to the oscillating voltage that is required for the operation of the pump circuit. The cut off voltage is thus synchronously set relative to the oscillating voltage such that low losses arise when loading C.sub.GS and an adequately high inhibit voltage can be built up when loading the pump capacitor.
