Abstract
A voltage generation circuit includes a voltage pump that receives a supply voltage and develops an output voltage responsive to a pump activation signal. A level detection circuit receives a pump-boost signal and is coupled to the voltage pump to receive the output voltage. The level detection circuit operates in a normal mode responsive to the pump-boost signal being inactive to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a first low threshold value. The level detection circuit operates in a demand-controlled mode responsive to the pump-boost signal being active to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a second low threshold value.
