Abstract
A method and apparatus for controlling a charge pump. A detection circuit is used to assert a detect signal when a power supply voltage exceeds a first threshold voltage and deassert the detect signal in response to a trigger. The detect signal is used to force a charge pump to operate in a mode that drives the capacitive node at its output to the target voltage with reduced latency. This is particularly useful for a device which may operate the charge pump in a reduced power mode which is designed to maintain the node voltage at reduced power rather than drive it to the degree necessary for reduced latency during power up.
