+5V, Low-Power μP Supervisory Circuits
with Adjustable Reset/Watchdog
_______________General Description
____________________________Features
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 capaci-
tors. A watchdog select pin extends the watchdog time-
out period to 500x. The reset function features immunity
to power-supply transients.
These four devices differ only in the structure of their reset
