Detailed Pin Configuration

The TPS3831K50DQNT has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Undervoltage detection: Monitors the voltage level and generates a reset signal when it falls below a certain threshold.
• Adjustable threshold voltage: Allows customization of the voltage level at which the reset signal is triggered.
• Power-on reset delay: Provides a delay before generating the reset signal after power-up, ensuring stable system operation.

Advantages and Disadvantages

Advantages

• Low-power consumption ensures minimal impact on overall system energy efficiency.
• Wide operating voltage range makes it compatible with various electronic systems.
