Title:
CIRCUIT CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2014138482
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a configuration capable of more efficiently concluding a cause of a circuit abnormality.SOLUTION: A circuit control device (20) comprises an abnormality detection unit (28), a drive signal output unit (24), a main control unit (21), and an information acquisition unit (25). The abnormality detection unit outputs an abnormality detection signal when detecting occurrence of an abnormality in a switching circuit (12). The drive signal output unit outputs a drive signal to a semiconductor switching element (13) when receiving a drive control signal. The main control unit outputs the drive control signal to the drive signal output unit and stops output of the drive control signal when receiving the abnormality detection signal. The information acquisition unit acquires information related to a switching circuit state different from the above abnormality synchronously with the drive control signal.
