ABSTRACT:
In accordance with the present invention, the above and other objects and advantages are obtained with a bootstrap circuit for a power MOS transistor in a high side configuration. Such circuit includes a first capacitor chargeable to a first voltage which is a function of the supply voltage of the power transistor. It further includes a second capacitor combined with the first capacitor so as to provide a second voltage which is higher than the first voltage and the threshold voltage of the power transistor.
