Working Principles

The MAX708SCSA+TG002 is designed to monitor the power supply voltage in electronic systems. It compares the supply voltage with a selected threshold voltage using an internal voltage reference. When the supply voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active for the specified timeout period, ensuring proper system initialization. Once the supply voltage rises above the threshold, the reset signal is automatically released.
