Abstract:
A method and apparatus is provided for outputting a reset signal during power-up until two conditions are satisfied. In one embodiment, the method and apparatus includes a voltage detector that provides a first output (“VO1”) when an output voltage of a regulator (“VREG”) exceeds a threshold voltage, thereby satisfying a first condition, a comparator receiving a first input voltage and a second input voltage, the comparator providing a second output (“VO2”) when the first input voltage exceeds the second input voltage, thereby satisfying a second condition, and a release circuit that outputs the reset signal unless the voltage detector provides VO1 while the comparator provides VO2.
