Integrierte Schaltung mit Gate-gesteuerten Leistungshalbleiter-Bauteilen

摘要

In a power integrated device having temperature monitoring circuits powered from input signal pulses, an overtemperature signal is memorized in a small capacitor (30 picofarads) to guarantee that the overtemperature signal will not be lost between two input pulses at a frequency greater than about 16 kHz. A larger charge storage capacitor (100 picofarads) is also added to store the input voltage Vcc needed to power the overtemperature circuits.
