Working Principles

The MAX6313UK47D1-T operates by comparing the supply voltage with the threshold voltage set using the TH pin. When the supply voltage drops below the threshold, the RESET pin is asserted low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX6313UK47D1-T finds applications in various fields, including:

1. Power Management: Ensuring proper system initialization and reliable operation during power-up.
2. Microcontroller Systems: Providing a reset signal to restart the microcontroller when the supply voltage falls below the threshold.
3. Industrial Control Systems: Monitoring critical voltage levels to prevent damage or malfunctioning of equipment.
4. Automotive Electronics: Resetting electronic control units (ECUs) in case of voltage dips or fluctuations.
5. Battery-Powered Devices: Preserving battery life by initiating a shutdown or sleep mode when the voltage drops below a certain level.
