  • Charge pump circuit related to overvoltage
    Patent number: 11936295
    Abstract: A charge pump circuit is provided, comprising: a first charge pump having an input terminal for receiving a supply voltage and configured to boost the received supply voltage to provide at an output terminal of the first charge pump a first charge pump voltage; a second charge pump having an input terminal coupled to the output terminal of the first charge pump for receiving the first charge pump voltage and configured to boost the received first charge pump voltage to provide at an output terminal of the second charge pump a second charge pump voltage, and a voltage drop sensing device configured to detect drops in the first charge pump voltage and to deactivate second transistors of bypass units associated to the disabled charge pump stages when a drop in the first charge pump voltage is detected.
    Type: Grant
