Working Principles

The ADM8690ARNZ is a voltage supervisor IC that continuously monitors the supply voltage of a digital system. It compares the voltage with a preset threshold and generates a reset signal when the voltage falls below the threshold. The reset signal remains active until the supply voltage rises above the threshold or a timeout period elapses.

The device also includes a manual reset input (MR) that allows the system to be reset externally. The MR input is debounced to prevent false triggering. The reset timeout period can be selected using external capacitors, providing flexibility in system design.

Detailed Application Field Plans

  • Microprocessor-based systems
  • Embedded systems
  • Industrial control systems
  • Consumer electronics
  • Battery-powered devices
  • Automotive electronics
