ABSTRACT:
A load short-circuit protective circuit device having broad protective operation range and capable of maintaining protective operation until short-circuit of output transistors is released (reset) without using thyristor circuit has an output transistor for generating power amplified signal, detection circuit for detecting a collector current and a collector voltage of the output transistor; and a protective operation circuit for performing protective operation for the output transistor when the current detected by the detection circuit reach predetermined current value and the voltage detected by the detection circuit enters within a set value range.
