AI summary

A power supply management device includes a first input terminal that receives an input voltage, and a first power supply circuit that outputs a voltage obtained by converting the input voltage. The first power supply circuit further outputs a first voltage responsive to a first signal being received by the first input terminal. The first power supply circuit yet further outputs a second voltage responsive to a second signal different from the first signal being received by the first input terminal.
