The MAX6301–MAX6304* low-power microprocessor
(µP) supervisory circuits provide maximum adjustability
for reset and watchdog functions. The reset threshold
can be adjusted to any voltage above 1.22V, using
external resistors. In addition, the reset and watchdog
timeout periods are adjustable using external capacitors.
A watchdog select pin extends the watchdog timeout
period to 500x. The reset function features immunity
to power-supply transients.
These four devices differ only in the structure of their reset
outputs (see the Selector Guide in the full data sheet). The MAX6301–MAX6304 are available in the space-saving 8-pin µMAX® package, as well as 8-pin PDIP and SO packages.
