Functional Features

  • Monitors the power supply voltage continuously.
  • Generates a reset signal when the voltage falls below the selected threshold.
  • Provides a manual reset input for immediate system reset.
  • Offers various threshold voltage and reset timeout period options for flexibility.

Advantages and Disadvantages

Advantages: - Low-power consumption. - Precision voltage monitoring. - Small package size. - Wide operating temperature range.

Disadvantages: - Limited threshold voltage and reset timeout period options. - Requires an external capacitor for operation.

Working Principles

The MAX708SEUA+T operates by comparing the power supply voltage with a reference voltage. When the voltage falls below the selected threshold, the reset output is activated, indicating a power failure. The reset signal remains active until the voltage rises above the threshold or a manual reset input is triggered.
