摘要: According to one embodiment, a current detection circuit includes a current detection part including an operational amplifier configured to compare a first voltage proportional to a load current with a second voltage proportional to a detection current. The current detection part is configured to output the detection current. The current detection circuit includes an adjustment part configured to generate data in accordance with a result of comparing a monitor voltage proportional to the detection current with a reference voltage, and to adjust an input offset of the operational amplifier.
