Abstract
A cascoded power switch includes a high-side (HS) switch coupled between an output node configured to provide an output voltage and a first voltage supply terminal configured to provide a first voltage supply, and a low-side (LS) switch coupled between the output node and a second voltage supply terminal configured to provide a second voltage supply. The LS switch includes a first transistor coupled between a middle node and the second voltage supply terminal, and a second transistor coupled between the middle node and the output node. The LS driver has a voltage monitoring circuit configured to receive a first control signal which, when negated, turns off the HS switch. The voltage monitoring circuit includes a logic circuit having a first input configured to receive the first control signal and a second input coupled to the middle node, and an output coupled to a control electrode of the first transistor.
