1. A voltage monitor for sensing the output voltage of a voltage source and producing an indication when said output voltage falls below a threshold voltage, said voltage monitor comprising:

  • voltage sensing means for sensing said output voltage and including means for comparing said output voltage with said threshold voltage and generating an output when said output voltage is less than said threshold voltage;

    status storage means coupled to said voltage sensing means for storing said output and generating an accumulated status;

    comparator means for comparing said accumulated status with a first predetermined number when said output voltage has been sensed a second predetermined number of times; and

    output means for providing said indication when said accumulated status is equal to or greater than said first predetermined number.
