Abstract
A system to monitor a MOSFET, the system including a switching arrangement configured to switchably isolate a gate terminal of the MOSFET and a source terminal of the MOSFET from a gate-control voltage source and a test circuit configured to detect a change in a gate-to-source voltage of the MOSFET over a test period, the test period occurring while the gate terminal and the source terminal are isolated.
