---

| | --| VDD | --| GND | --| MR | --| RESET | --| VIT | |_______| ```

• VDD: Power supply input
• GND: Ground reference
• MR: Manual reset input
• RESET: Output signal indicating system reset status
• VIT: Threshold voltage selection input

Functional Features

1. Voltage Monitoring: The TPS3839K50DQNT continuously monitors the input voltage and compares it with the selected threshold voltage.
2. Reset Generation: When the monitored voltage falls below the threshold, the device generates a reset signal to initiate system recovery.
3. Adjustable Threshold: The threshold voltage can be set according to the specific requirements of the application.
4. Reset Time Delay: The device offers various reset time delay options to accommodate different system response times.

Advantages and Disadvantages

Advantages

• Low-power consumption ensures minimal impact on overall system efficiency.
• Wide operating voltage range makes it compatible with a variety of electronic systems.
• High accuracy in voltage monitoring enhances system reliability.
• Adjustable threshold voltage allows customization for specific applications.
• Reset time delay options provide flexibility in system response.

Disadvantages

• Limited number of threshold voltage options may not cover all possible voltage monitoring scenarios.
• Manual reset input may require additional external components for proper functionality in certain applications.

Working Principles

The TPS3839K50DQNT operates by comparing the input voltage with the selected threshold voltage. If the input voltage drops below the threshold, the device triggers a reset signal. This reset signal remains active until the input voltage rises above the threshold and the reset time delay elapses.

Detailed Application Field Plans

The TPS3839K50DQNT finds applications in various fields, including but not limited to: - Power management systems - Battery-powered devices - Industrial automation - Automotive electronics - Consumer electronics
