  • Adjustable threshold voltage allows customization for different system requirements.
  • Reset output remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.
  • Manual reset input allows for immediate system reset if required.

Advantages and Disadvantages

Advantages: - Low-power consumption, suitable for battery-powered applications. - Precision voltage monitoring ensures reliable system operation. - Adjustable threshold voltage provides flexibility for various voltage levels. - Small package size saves board space.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited number of pins for additional functionality.

Working Principles

The MAX848ESE+T operates by continuously monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the set threshold, the reset output is activated, indicating a low-voltage condition. The reset output remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses. The manual reset input allows for an immediate system reset if required.
