Introduction

The MAX821LUS is a simple reset/power-on reset (POR) supervisor that monitors a single supply voltage. It provides an active-low reset signal that can be used to hold a microcontroller or other digital system in reset until the supply voltage is at a safe level. The reset timeout period is adjustable via an external resistor, allowing the reset time to be tailored to the specific requirements of the application.
