ABSTRACT:
A power down reset circuit for asserting a signal when a first VDDvoltage falls below a voltage threshold. The circuit has at least one diode coupled to the first VDDvoltage. The at least one diode is configured to produce a second voltage. At least one capacitor is coupled to the at least one diode to maintain the second voltage. A voltage detector asserts a signal when the first VDDvoltage drops below a threshold level. The voltage detector is powered by the second voltage and is coupled to the at least one diode.
