Abstract
A power circuit includes a power transistor flowing a power current to a ground according to the voltage of a driving node, a driving circuit, a first pre-driver, a second pre-driver, and a hysteresis circuit. The driving circuit includes a high-side transistor providing a supply voltage to the driving node according to a high-side voltage of a high-side node, a low-side transistor coupling the driving node to the ground according to a first internal signal, and a charge pump coupled to the high-side node and the driving node and generating the high-side voltage that exceeds the supply voltage according to the first internal signal. The first pre-driver receives a second internal signal to generate the first internal signal. The second pre-driver receives a third internal signal to generate the second internal signal. The hysteresis circuit receives a control signal to generate the third internal signal.
