Detailed Pin Configuration

The TPS3831A09DQNR has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Undervoltage detection: The TPS3831A09DQNR monitors the input voltage and generates a reset signal when it falls below a certain threshold.
• Power-on reset delay: It provides a delay time to ensure stable power supply before releasing the reset signal.
• Manual reset: An external push-button can be connected to the RESET pin for manual reset functionality.
• Low-power consumption: The device operates with minimal power consumption, making it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring
• Wide operating voltage range
• Small package size for space-constrained designs
• Low-power consumption
• Robust design for harsh environments

Disadvantages

• Limited number of pins for additional functionalities
• Requires an external push-button for manual reset

Working Principles

The TPS3831A09DQNR works by comparing the input voltage with a fixed threshold. When the voltage falls below the threshold, the device generates a reset signal. This signal remains active until the voltage rises above the threshold or a manual reset is triggered.
