Zusammenfassung:Described is a power management driver and a display device having the power management driver are provided, including a first power supply configured to supply a first voltage to a first driving power terminal of a pixel through a power line during a sensing period, and supply a second voltage to the first driving power terminal of the pixel through the power line during a display period; a controller configured to control timing at which the first voltage is output and timing at which the second voltage is output during a transition period between the display period and the sensing period in response to a sensing control signal; and a fault detector configured to detect a fault in the power line based on a current flowing through an output terminal during the sensing period.
