Method and apparatus for protecting monitor circuit from fault condition |
摘要 |
A method and apparatus for improving the fault protection of a monitor circuit is provided by coupling an input protection circuit to an output section. The input protection circuit may include a fusible device that limits or removes a fault condition present at an input to the input protection circuit. The fusible device may be, for example, a resettable positive temperature coefficient ("PTC") device configured to limit the current passing through it to a predetermined level once it reaches a predetermined temperature. A resistive element may be thermally coupled to the PTC device to assist it reaching the predetermined temperature. The monitor circuit may further be configured to generate a sensory signal in response to a fault condition.
