Overview
19-1078; Rev 0; 6/96 +5V, Low-Power µP Supervisory Circuits with Adjustable Reset/Watchdog _______________General Description The MAX6301/MAX6302/MAX6303/MAX6304* lowpower 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 Selector Guide).
The MAX6301–MAX6304 are available in the space-saving 8-pin µMAX package, as well as 8-pin DIP/SO.
