Working Principles

The MAX6424UK25+T is a voltage supervisor IC that continuously monitors the supply voltage of a system. It compares the supply voltage with the selected threshold voltage and generates a reset signal when the supply voltage falls below the threshold. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

The manual reset input allows an external signal to override the monitoring function and force a reset. This feature is useful during system testing or when a controlled reset is required.

Detailed Application Field Plans

• Microcontroller-based systems
• Digital devices requiring reliable power-on reset functionality
• Battery-powered applications
• Portable electronics
• Industrial control systems
