Patent abstract
A low-side driving circuit forms a power conversion apparatus together with a power transistor to be driven. A protection circuit generates a protection signal S1. An alarm control circuit changes an electrical state of a fail terminal according to the protection signal S1. A judgment circuit compares a voltage VFO at a fail (FO) terminal with a predetermined threshold value, and generates a judgment signal S2 that indicates the comparison result. A control logic circuit controls the state of the power transistor based on the judgment signal S2 and the protection signal S1.
