5.2.1.1 Design Requirements

For this design, follow these design requirements:

  • UV_Alert (logic low output) when the 24V suply is less than 19.2V
  • OV_Alert (logic low output) when the 24V suply is greater than 30V
  • Current dissipated in the resistor string is 30uA
  • Comparator operates from the 5V supply

  • 2.5V external reference is utilized
