Abstract: Disclosed is a power management device which includes a storage unit, a comparison control unit, a switching unit, and a power transmission control unit. The storage unit includes storage nodes. The comparison control unit outputs switch control signals based on results of comparing voltage levels of the storage nodes and threshold voltage pairs in a one-to-one correspondence. The switching unit includes switches connecting one of the storage nodes to a transmission node. A first switch is turned off when a voltage level of a first storage node is smaller than or equal to a first lower limit voltage. A second switch is immediately turned on when a voltage level of a second storage node is greater than or equal to a second upper limit voltage and when the first switch is turned off.
