Abstract
A power management circuit is disclosed that includes a boost converter, a pass transistor, and an overcurrent detect circuit. The boost converter is configured to convert an input voltage into a first power supply voltage. The pass transistor is configured to transfer the first power supply voltage as a second power supply voltage after a predetermined time from a time point at which the first power supply voltage is activated. The overcurrent detect circuit is configured to perform an overcurrent detect operation by sensing a current flowing through the pass transistor. A display device is also disclosed that includes the power management circuit.
