Detailed Pin Configuration

The TPS3825-33DBVRG4 has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the voltage level continuously.
• Generates a reset signal when the voltage drops below the threshold.
• Adjustable reset timeout period allows customization based on system requirements.
• Provides a stable reset output during power-up and power-down sequences.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range enables compatibility with various systems.
• High accuracy ensures reliable voltage monitoring.
• Adjustable reset timeout period offers flexibility in system design.

Disadvantages

• Limited to a single threshold voltage (3.3V).
• SOT-23 package may not be suitable for applications requiring higher power dissipation.

Working Principles

The TPS3825-33DBVRG4 operates by comparing the monitored voltage with the preset threshold voltage (3.3V). If the voltage falls below this threshold, the device generates a reset signal. The reset timeout period can be adjusted to control the duration of the reset signal.
