Title:
半導体装置及びそれを備えた電子制御システム
Document Type and Number:
Japanese Patent JP6591295
Kind Code:
B2
Abstract:
According to one embodiment, a semiconductor device includes external terminals supplied with the pair of voltage signals based on a detection result of a resolver through first and second input resistances, respectively, an operation amplifier configured to amplify a potential difference between the pair of the voltage signals supplied to the external terminals, a feedback resistance disposed between an output terminal of the operation amplifier and one of two input terminals thereof, switches disposed between the two input terminals of the operation amplifier and the external terminals, respectively, and a short-circuit failure detection circuit configured to detect whether or not a short-circuit failure has occurred in the resolver based on a voltage level of each of the external terminals in a state where the switches are in an off-state.
