Abstract
A cascoded power switch includes a high-side (HS) switch between an output node and a first voltage supply terminal and a low-side switch. The HS switch includes a first, second, and third transistor in series between the first voltage supply terminal and the output node, and a fourth, fifth, and sixth transistor in series between the first voltage supply terminal and the output node. The first and fourth transistors are in parallel, the second and fifth transistors are in parallel, and the third and sixth transistors are in parallel. A HS driver circuit begins turning on the first transistor in response to assertion of a first control signal and delays turning on the fourth transistor until both the first and second controls signal are asserted. A voltage monitoring circuit includes logic which asserts the second control signal in response to a rise of an output voltage at the output node.
