Detailed Pin Configuration

The TPS3851H33EDRBR has three pins:

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

Functional Features

• Undervoltage Detection: The TPS3851H33EDRBR monitors the voltage level and triggers a reset signal when it falls below the set threshold.
• Adjustable Threshold: The threshold voltage can be adjusted to suit different system requirements.
• Delay Timer: The built-in delay timer ensures that the reset signal remains active for a specified duration after the voltage returns to the normal range.
• Power-On Reset: The device generates a reset signal upon power-up to ensure a controlled system startup.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows for compatibility with various systems.
• High accuracy ensures reliable voltage monitoring.
• Adjustable threshold voltage provides flexibility in different scenarios.
