概述

Description

MAX865EUA is a Maxim Integrated (now Analog Devices) voltage-monitor/reset supervisory IC in the MAX865 family. It monitors one or more supply rails and asserts a defined reset output to a microcontroller or logic device when the rail falls below a preset threshold, ensuring proper power-on/power-down sequencing. Typical features include undervoltage detection with selectable thresholds, a reset output (active-low or active-high, with fast response), and low quiescent current. Some variants also include a watchdog timer or a manual reset input. Applications include MCU/FPGA supervision, brown-out protection, and safe power sequencing in embedded and portable systems. For exact electrical characteristics, pinout, timing, and packaging, consult the MAX865EUA datasheet.

Package

I don’t have live web access to look up the MAX865EUA datasheet. Please attach the datasheet or allow me to fetch it, and I’ll provide the exact package type (e.g., SOT‑23, µMAX, SC70) in one short sentence.
