Abstract
A circuit, which may be included as part of an integrated circuit chip including a microprocessor or other device needing initialization when being powered up, generates a reset signal at a time determined by the voltage rise characteristics of the power supply to the device when either initially turned on to the device or recovering from a voltage dip. A power supply sensing node of the circuit is initially discharged to ground potential in order to eliminate any effect of a charge on the node on the timing of the reset signal, such as might be generated by an ambient electromagnetic field.
