Product Introduction

Overview

The MAX803SQ120T1G is a cost-effective system supervisor circuit designed by onsemi to monitor the VCC in digital systems and provide a reset signal to the host processor when necessary. This device is part of the MAX803 series and is optimized for low power consumption and high reliability. It is particularly suitable for battery-powered applications due to its low supply current of 0.5 μA at 3.2 V. The MAX803SQ120T1G is available in a compact SC-70-3 package, making it ideal for space-constrained designs.
