MAX809S - UMW

Manufacturer Part Number

MAX809S

Manufacturer

Maxim Integrated

Introduction

The MAX809S is a voltage detector that monitors a single supply voltage and provides an active-low reset output when the voltage drops below the preset threshold. It is designed for use in microprocessor-based systems to detect power-supply failures and initiate an orderly shutdown. The MAX809S offers a precise 2.93V threshold with a maximum tolerance of ±1% over the entire operating temperature range.
