Working Principles

The ADM693AN is designed to monitor the supply voltage of a digital system. It compares the supply voltage with a preset threshold and generates a reset signal when the voltage falls below this threshold. The reset signal remains active until the supply voltage rises above the threshold and a specified timeout period elapses. The device also includes a manual reset input that can override the monitoring function and force a reset.

Detailed Application Field Plans

• Microprocessor-based systems: Provides reliable reset signals to ensure proper initialization and operation.
• Embedded systems: Monitors power supply voltage to prevent data corruption or system malfunction.
• Battery-powered devices: Efficiently manages power consumption by initiating resets when the voltage drops below a certain level.
• Industrial control systems: Ensures stable operation by resetting the system in case of voltage fluctuations or power interruptions.

Detailed and Complete Alternative Models

• ADM6315: Voltage Monitor with Adjustable Reset Timeout Period
• MAX809: Supervisory Circuits with Multiple Reset Threshold Options
• TPS3808: Precision Voltage Supervisor with Programmable Delay Time
