Abstract
A device includes a function circuit that operates based on power provided by a first positive supply voltage and a first negative supply voltage, a monitoring circuit that operates based on power provided by a second positive supply voltage and a second negative supply voltage and that generates a first monitor signal based on monitoring an operation of the function circuit, and an output circuit that generates a second monitor signal based on monitoring the first positive supply voltage, generates a third monitor signal based on monitoring the second positive supply voltage, and generates an output signal that is output through one or more output pins, based on the first monitor signal, the second monitor signal, and the third monitor signal.
