```

---

| | --| VDD GND |-- Pin 1: Ground --| VIN OUT |-- Pin 2: Output --| DELAY SENSE|-- Pin 3: Sense Input --| RESET |-- Pin 4: Reset Output |___________| ```

Functional Features

• Under-voltage detection: The TPS3707-30DGNR monitors the input voltage and asserts a reset signal when it falls below the threshold voltage.
• Adjustable delay time: The device allows users to set the delay time before asserting the reset signal.
• Open-drain output: The reset output is an open-drain configuration, allowing for flexibility in connecting to other devices.

Advantages and Disadvantages

Advantages

• Wide operating voltage range
• Low quiescent current consumption
• Adjustable delay time for customization
• Small package size for space-constrained applications

Disadvantages

• Limited threshold voltage options (only 3.0V available)

Working Principles

The TPS3707-30DGNR operates by continuously monitoring the input voltage. When the voltage falls below the threshold level, the device asserts a reset signal, indicating a power failure or abnormal voltage condition. The delay time can be adjusted to allow for transient voltage fluctuations without triggering a reset. The open-drain output allows for easy integration with other devices.

Application Field Plans

The TPS3707-30DGNR finds applications in various fields, including: 1. Power supply monitoring in industrial control systems. 2. Battery-powered devices to prevent over-discharge. 3. Automotive electronics for voltage supervision. 4. Home automation systems for fault detection. 5. Medical equipment to ensure reliable power supply.
