Techniques are described for determining whether a switch circuit experienced one of a latched overload condition and an open load with no input voltage condition. In the techniques, a first diagnostic signal is output if the switch circuit experienced the latched overload condition. Also, in the techniques, a second, different diagnostic signal is output if the switch circuit experienced the open load with no input voltage condition.
