ABSTRACT:
An electronic circuit device having a protection circuit for protecting a switching system electronic circuit when a ground terminal is removed from the device. The protection circuit includes a detection circuit for detecting the ground terminal has been removed from ground as a change in an electronic potential of the ground terminal, an input cut-off circuit connected between an input terminal and the electronic circuit to control an operation of the electronic circuit, a low voltage protection circuit for controlling an operation of the electronic circuit in response to an output signal from the detection circuit, and a memory circuit for controlling an operation of the input cut-off circuit in response to both output signals from the detection circuit and the low voltage protection circuit.
