Abstract
A gate driver IC includes a first diode, a second diode, a first comparator, a second comparator, and a judgement circuit. The first comparator compares a first potential difference between both ends of the first diode and a first threshold. The second comparator compares a second potential difference between both ends of the second diode and a second threshold. Based on comparison results of the first comparator and the second comparator, the judgement circuit determines occurrence of disconnection.
