Working Principles

The MAX6314US28D4+T is designed to monitor the power supply voltage of a system. It compares the supply voltage with a threshold voltage set by the TH pin. When the supply voltage drops below the threshold, the RESET pin becomes active-low, generating a reset signal. The reset timeout period determines how long the reset signal remains active after the supply voltage returns to normal.

Detailed Application Field Plans

• Battery-powered devices: Provides reliable power supply monitoring and reset generation for portable electronics, IoT devices, and wearables.
• Embedded systems: Ensures proper system initialization and prevents erratic behavior during power-up or brownout conditions.
• Industrial control systems: Enhances the stability and reliability of critical equipment by monitoring power supply integrity.
• Automotive electronics: Protects sensitive components from voltage fluctuations and ensures safe operation of automotive systems.
