GROUND FAULT DETECTION CIRCUIT |
| 摘要 |
A ground fault detection circuit comprising a fuse and a fuse detect circuit. The fuse and the fuse detect circuit are arranged to be coupled in parallel between a reference point and a second point of a monitored circuit for which ground faults are to be detected. The fuse detect circuit is further arranged to detect a fuse break indicative of a ground fault condition and disable at least a portion of the monitored circuit. |

1. A ground fault detection circuit comprising:
a fuse; a fuse detect circuit; the fuse and the fuse detect circuit being arranged to be coupled in parallel between a reference point and a second point of a monitored circuit for which ground faults are to be detected, wherein the fuse detect circuit comprises a voltage monitor coupled in parallel between the reference point and the second point of the monitored circuit, wherein the ground fault detection circuit further comprises a potential divider coupled between the voltage monitor and the fuse, the potential divider being directly coupled to the fuse, and wherein the fuse detect circuit is further arranged to: detect a fuse break indicative of a ground fault condition; and disable at least a portion of the monitored circuit. |
