... Detailed Description RESET /RESET Output A µP’s reset input starts the µ known state. The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860– MAX6869 µP supervisory circuits assert a reset to prevent code-execution errors during power-up, power-down, and brownout conditions. The MAX6854/MAX6855/MAX6856/ MAX6858/MAX6860–MAX6869 reset output is guaranteed to be valid for V down to 1 ...

... Nanopower µP Supervisory Circuits with Manual Reset and Watchdog Timer Transient Immunity In addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, the MAX6854/ MAX6855/MAX6856/MAX6858/MAX6860–MAX6869 are relatively immune to short-duration supply transients, or glitches. The Maximum V Transient Duration vs. Reset CC Threshold Overdrive graph in the Typical Operating Characteristics shows this relationship ...

... Nanopower µP Supervisory Circuits with Manual Reset and Watchdog Timer input at different points in the program, rather than pulsing the watchdog input high-low-high or low-high- low. This technique avoids a stuck loop, in which the watchdog timer would continue to be reset inside the loop, keeping the watchdog from timing out. ...
