    摘要: In a semiconductor device, a problem of heat generation and power loss is alleviated, and the semiconductor device is protected against the failure due to the overcurrent. The semiconductor device includes an IC chip having a large-current output. In the IC chip a measuring terminal is electrically connected with a first pad via a gold wire. A potential difference generated by the impedance of the gold wire is compared with a predetermined value. When the potential difference exceeds the predetermined threshold level, the semiconductor device operates to turn off a PMOS-type transistor.

    摘要: Disclosed is a signal transmission circuit device (200) including a feedback signal transmission unit (210) that feeds back a control output signal (Sout) as a feedback signal (Sf) to an input side circuit (200A). A logical comparison circuit (212) detects “mismatch” between input and output by performing logical comparison between a control input signal (Sin) and the feedback signal (Sf). When a state of “mismatch” between input and output occurs, a first pulse generating circuit (202) or a second pulse generating circuit (204) outputs a first correction signal (Sa1) or a second correction signal (Sa2) corresponding to a potential (high level or low level) of the control input signal (Sin), and corrects the control output signal (Sout) to the same potential (high level or low level) as the control input signal (Sin). With such configuration, the mismatch between input and output can be automatically corrected.
