ABSTRACT:
A power-on reset circuit device has a first power-on reset circuit which outputs a first reset signal, when an external power supply voltage reaches a first reference voltage, for resetting a DC-DC converter for producing a plurality of internal power supply voltages; a second power-on reset circuit which outputs a second reset signal, when the internal power supply voltage produced by the DC-DC converter reaches a second reference voltage, for resetting an internal circuit; and transistor switches for respectively inactivating the first power-on reset circuit and fixing the level of the first reset signal in response to the second reset signal. Power consumed by the power-on reset circuit device can be kept low because, in response to the second reset signal, the first power-on reset circuit is inactivated by the second power-on reset circuit. The power-on reset circuit device can be formed by a small number of circuit components required.
