Abstract
An overvoltage protection circuit for interposing between an input voltage and a supply voltage is described. The overvoltage protection circuit includes switch circuitry connected to and passing current between an input voltage node and a supply voltage node, the input voltage node corresponding to the input voltage and the supply voltage node corresponding to the supply voltage. Switch control circuitry senses the supply voltage and regulates current flow through the switch circuitry in response thereto.
