2. GND: This pin is connected to the ground.
3. OUT: This open-drain output pin provides a signal indicating the status of the monitored voltage level.

Functional Features

• Accurate voltage monitoring: The TPS3707-25DG4 ensures precise monitoring of voltage levels, preventing potential damage to electronic systems.
• Adjustable delay time: The device allows users to set the delay time according to their specific requirements.
• Open-drain output: The open-drain output provides flexibility in connecting to different systems.

Advantages and Disadvantages

Advantages

• Low quiescent current consumption helps conserve power in battery-operated devices.
• Wide operating temperature range enables usage in extreme environments.
• Adjustable delay time allows customization for specific applications.
• Small package size is suitable for space-constrained designs.

Disadvantages

• Limited voltage threshold options may not cater to all voltage monitoring needs.
• Lack of integrated hysteresis may require additional external components for noise immunity.

Working Principles

The TPS3707-25DG4 operates by comparing the monitored voltage level with a fixed threshold. When the voltage falls below the threshold, the open-drain output is activated, indicating a low voltage condition. The delay time can be adjusted to provide a stable output signal, preventing false triggering due to temporary voltage fluctuations.
