Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2015149731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit capable of detecting abnormality which has the potential to cause malfunction in signal transfer via an insulating element to output a stop signal to a control target.SOLUTION: The semiconductor integrated circuit according to the present embodiment comprises: a transmission circuit Tx1 for creating and outputting a transmission signal corresponding to transmission data VIN supplied from the outside; a receiving circuit Rx1 for regenerating the transmission data VIN on the basis of a received signal; an insulating element ISO1 for insulating the transmission circuit Tx1 and the receiving circuit Rx1 and transferring the transmission signal as the received signal; an abnormality detection part DT1 for detecting abnormality which has the potential to cause malfunction in signal transfer via the insulating element ISO1; and a control part CT1 fro outputting a stop signal regardless of the transmission data VIN supplied from the outside to the transmission circuit Tx1 when malfunction is detected by the abnormality detection part DT1.
