Abstract
Some of the embodiments of the present disclosure provide an apparatus for sensing a voltage level of an output voltage that is selected from at least two voltage supplies, including: a maximum voltage generator circuit configured (i) to determine a voltage supply among the at least two voltage supplies that has a higher voltage level and (ii) to output a maximum voltage signal having a voltage level corresponding to the higher voltage level; and a sensing module configured to selectively sense the output voltages, the sensing module comprising a switch circuit configured to apply the maximum voltage signal to completely turn off supply of the output voltage when the output voltage is not to be sensed at the sensing module.
