... Low-Power µP Supervisory Circuits with Adjustable Reset/Watchdog Detailed Description Reset Function/Output The reset output is typically connected to the reset input of a µP. A µP’s reset input starts or restarts the µ known state. The MAX6301–MAX6304 µP supervisory circuits provide the reset logic to prevent code-execution errors during power-up, power-down, and brownout conditions (see the Typical Operating Circuit ) ...
