Abstract
A charge pump circuit includes a first charge pump stage circuit coupled in series with a second charge pump stage circuit. A discharge circuit operates to discharge the charge pump circuit. The discharge circuit includes: a first switched circuit coupled to a first output of the first charge pump stage circuit and configured, when actuated, to discharge the first output; and a second switched circuit coupled to a second output of the second charge pump stage circuit and configured, when actuated, to discharge the second output. A discharge control circuit actuates the first switched discharge circuit to discharge the first output and then, after the first output is fully discharged, actuates the second switched discharge circuit to discharge the second output.
