ABSTRACT:
A power supply potential rising detection circuit comprises a transistor having a control gate and a floating gate, connected in series with a load element between first and power supply terminals. A first potential is applied to the control gate, the first potential being dependent on the power supply potential at the first power supply terminal. A switching element is operatively connected to the floating gate and controlled by a second potential dependent on the power supply potential, and reduces the potential of the floating gate and turns off the transistor when the power supply potential reaches a predetermined value, thereby outputting a power supply potential rising detection signal from the series connection point between the load element and the transistor.
