According to one embodiment, a hot-swap controller includes an output circuit, a voltage generator, a detector, and a compensator. The output circuit is configured to generate an enabling signal. The enabling signal is capable of switching an output signal of a semiconductor device provided on a hot-swap board to be disabled when a supply voltage is lower than a release voltage and to be enabled when the supply voltage is higher than the release voltage. The voltage generator includes a bias transistor supplied with the supply voltage and is configured to generate a first voltage. The first voltage varies depending on the supply voltage and is referred to detect the release voltage. The detector is configured to detect the first voltage. The compensator is configured to compensate the first voltage to a certain value depending on an output of the detector. |
