Abstract
A circuit apparatus includes an input end, an output end, an enable module, a first function module and a second function module. The enable module couples to the input end for receiving an input voltage and outputs an enable signal while the input voltage falls within a first voltage scope. The first function module couples to the enable module and the output end, and performs a test mode according to the enable signal so as to output a test result to the output end. The second function module couples to the input end for receiving the input voltage via the input end and performs a standard mode while the input voltage falls within a second voltage scope.
Claims10
A circuit apparatus, comprising:
- an input end;
- an output end;
- an enable module, which is coupled to the input end for receiving an input voltage and outputs an enable signal when the input voltage falls within a first voltage scope;
- a first function module, which is coupled to the enable module and the output end, and performs a test mode according to the enable signal thereby outputting a test result to the output end;
- and
- a second function module, which is coupled to the input end for receiving the input voltage via the input end and performs a standard mode when the input voltage falls within a second voltage scope.
