Product Introduction

Overview

The MAX809JTRG, produced by onsemi, is a cost-effective system supervisor circuit designed to monitor the supply voltage (VCC) in digital systems and provide a reset signal to the host processor when necessary. This device is part of the MAX809 series, which includes the MAX809 and MAX810, and is optimized for low supply current and high reliability. The MAX809JTRG is particularly suited for battery-powered applications and critical microprocessor power supply monitoring due to its low power consumption and robust transient immunity.
