Manufacturer Part Number

DS1834AU+

Manufacturer

analog-devices

Introduction

The DS1834AU+ is a multi-voltage supervisor that monitors two independent supply voltages, typically 3.3V and 5V. It provides an active-low reset signal when either of the monitored voltages falls below its respective threshold. The DS1834AU+ is designed to simplify power-on and power-down sequencing in microprocessor-based systems.
