Product Introduction

Overview

The MAX809MTRG, produced by onsemi, is a cost-effective system supervisor circuit designed to monitor the supply voltage (V_CC) in digital systems and provide a reset signal to the host processor when necessary. This device is part of the MAX809 and MAX810 series, which are optimized to reject fast transient glitches on the V_CC line. The MAX809MTRG requires no external components and is suitable for battery-powered applications due to its low supply current of 0.5 µA at V_CC = 3.3 V.
