Detailed Pin Configuration

The TPS389020DSER features a standard 6-pin configuration:

1. GND (Ground): Connected to the ground reference of the system.
2. VDD (Supply Voltage): Connected to the positive supply voltage of the system.
3. MR (Manual Reset): Allows for manual reset of the device.
4. RESET (Reset Output): Provides an active low signal indicating a voltage fault condition.
5. VIT (Voltage Input): Connected to the voltage being monitored.
6. NC (No Connection): This pin is not internally connected and should be left unconnected.

Functional Features

• Undervoltage Detection: The TPS389020DSER monitors the input voltage and generates a reset signal when it falls below a specified threshold.
• Manual Reset: The device includes a manual reset input, allowing for system restarts when necessary.
• Power-On Reset Delay: It incorporates a power-on reset delay to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages

• High accuracy in voltage monitoring.
• Wide input voltage range.
• Low power consumption.
• Compact package for easy integration.
• Reliable and robust performance.
