+5V, Low-Power, µP Supervisory Circuits with Adjustable Reset/Watchdog

Overview

Status

Active: In Production.

Description

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.
