Working Principles

The MAX6414UK46+T is designed to monitor the voltage level of a power supply. It compares the supply voltage with a preset threshold voltage. When the supply voltage falls below the threshold, the reset output is activated. The reset signal remains active until the supply voltage rises above the threshold or a manual reset input is triggered.

Detailed Application Field Plans

• Battery-powered devices: The MAX6414UK46+T can be used to monitor the battery voltage and initiate a reset when it drops below a critical level, preventing unreliable operation.
• Microcontroller systems: By connecting the reset output to the microcontroller's reset pin, the MAX6414UK46+T ensures that the system restarts properly in case of a power supply failure.
• Industrial control systems: Voltage monitoring and reset functionality provided by the MAX6414UK46+T enhance the reliability of critical control systems.
