摘要:
A loss-of-ground protection circuit for an electronic relay including a control circuit driving a power transistor, and at least one cutoff transistor having a grounded control terminal, the cutoff transistor being interposed between the control circuit and a control terminal of the power transistor, and having a polarity such that loss of ground will cause the cutoff transistor to turn off.
