ABSTRACT:
A high voltage generating device includes a charge pump generating high voltage by boosting a power supply voltage and supplying it to a load, a timer measuring activation time of the charge pump and outputting a signal after a prescribed time period, an A-D converter converting an output voltage of the charge pump into a digital value in response to the signal and outputting four bit binary data, and a current limiting circuit including four P channel MOS transistors connected in parallel between a power supply node and a drain of an N channel MOS transistor which has a gate receiving the digital value output from the A-D converter.
