APPLICATION NOTE 2853

Supervisors in Multivoltage Systems

By: Greg Sutterlin

Abstract: As processors become more complex, ensuring proper operation becomes more involved and more is demanded from supervisory circuits.
  • Multi-voltage supervisors provide power-on reset, proper sequencing, and continuous voltage monitoring.
  • The lower voltage requirements in today's state-of-the-art processors demands the use of new low-voltage monitors.
  • Modern supervisors provide additional functions such as watchdog timers, manual reset input, and power fail comparators.
