Abstract
A supply switch circuit is provided for implementing a switchable on-chip high voltage supply. A stack of transistors is coupled between an on-chip high voltage supply and a circuit node. A control signal is coupled to the stack of transistors for selectively switching the high voltage supply to the circuit node. The control signal is coupled to a voltage divider included with the stack of transistors to limit a maximum node voltage within the stack of transistors.
