摘要： Protecting the devices of a charge pump includes the connection of a high-voltage transistor between the output node of the charge pump and the load being supplied, and in controlling this transistor with a fraction of the output voltage of the charge pump. This control is accomplished by connecting the control node of the high-voltage transistor to a node of connection between two stages of the multi-stage charge pump onto which a fraction of the controlled output voltage of the multi-stage charge pump is produced. The high-voltage output transistor protects the low voltage devices of the multi-stage charge pump, by preventing the controlled output voltage from undergoing excessively abrupt variations, that could damage the transistors of the last stage of the charge pump.
