| 发明名称 | Circuit arrangement with an overcurrent fuse | ||
| 摘要 | A circuit arrangement includes a semiconductor switch having a control terminal and a load path. A drive circuit is coupled to the control terminal of the semiconductor switch. The drive circuit has a current measuring arrangement for determining a load current flowing through the load path and is designed to prevent the semiconductor switch from being driven in the off state if the load current exceeds a predetermined load current threshold value. A fuse is coupled in series with the load path of the semiconductor switch triggers if a triggering condition dependent at least on the load current is present. | ||

| 主权项 | 1. A circuit comprising: a drive circuit comprising an output terminal configured to be coupled to a control terminal of a semiconductor switch having a load path coupled in series with a fuse,an input terminal for requesting an on state and an off state of the semiconductor switch, anda current measuring arrangement for determining a load current flowing through the load path, wherein the drive circuit is configured to prevent the semiconductor switch from being driven in the off state if the load current exceeds a first load current threshold. | ||
