Abstract
A power-up initial circuit includes a power-up control unit, a first switch and a second switch. The power-up control unit is used for receiving a high voltage start-up signal, and generating a first power-up control signal. The first switch has a first terminal for receiving an external voltage, a second terminal for coupling to the power-up control circuit for receiving the first power-up control signal, and a third terminal. The second switch has a first terminal coupled to the third terminal of the first switch, a second terminal for coupling to the power-up control circuit for receiving the first power-up control signal, and a third terminal for coupling to a high voltage generator.
