Detailed Pin Configuration

The TPS3820-33QPDBVRQ1 has the following pin configuration:

1. GND (Ground)
2. VDD (Supply Voltage)
3. MR (Manual Reset)
4. RESET (Reset Output)
5. N/C (No Connection)

Functional Features

• Voltage monitoring: The TPS3820-33QPDBVRQ1 continuously monitors the supply voltage and provides a reset signal when the voltage falls below the specified threshold.
• Manual reset: The MR pin allows for manual reset, enabling system restart or initialization.
• Open-drain output: The reset output is an open-drain configuration, allowing for flexibility in connecting to other devices.

Advantages and Disadvantages

Advantages

• Low quiescent current ensures minimal power consumption.
• Precision voltage threshold guarantees accurate monitoring.
• Small package size enables usage in space-constrained applications.
• Open-drain output offers versatility in system integration.

Disadvantages

• Limited voltage supervision range (3.3V).
• Reset timeout period may not be suitable for all applications.

Working Principles

The TPS3820-33QPDBVRQ1 operates by continuously comparing the supply voltage with a precision voltage threshold. When the voltage drops below this threshold, the reset output is activated, indicating a low-voltage condition. The reset output remains active until the voltage rises above the threshold or a manual reset is triggered.
