Abstract
Methods and apparatus for monitoring the integrity of an insulative material. A monitoring module detects a leakage current corresponding to an injection signal into the insulative material by a signal source. An output can provide an insulation fault signal when the leakage current is greater than a given threshold.
Claims28
An integrated circuit package, comprising:
- a first I/O pin configured to be coupled to an insulative material;
- a second I/O pin configured to output an insulation fault signal;
- and
- a monitoring module coupled to the first I/O pin, the monitoring module comprising a filter module and a current detection module configured to detect a leakage current on the first I/O pin corresponding to an injected signal into the insulative material by a signal source, the monitoring module further comprising an output module configured to output an active state on the insulation fault signal when the leakage current is greater than a given threshold.
