Abstract
A system includes a first driver circuit configured to drive a first switch, a second driver circuit configured to drive a second switch, and a controller arranged to control the first driver circuit and second driver circuit. The controller has an output terminal configured to output a control signal to a first level or a second level, the output terminal being connected to a control terminal of the first driver circuit and to an output terminal of the second driver circuit. The second driver circuit is arranged to drive the output terminal to the first level to indicate an error related to the second driver circuit. The first driver circuit is arranged to drive the first switch to operate in a safe state based on a determination that the control signal on the control terminal is at the first level.
