3. VDD (Internal Regulator Output)
4. MR (Manual Reset Input)
5. TH (Threshold Input)
6. CT (Delay Time Capacitor)
7. DO (Open-drain Output)
8. NC (No Connection)

Functional Features

• Accurate voltage monitoring and supervision
• Adjustable delay time for customized applications
• Open-drain output for easy integration with other circuitry
• Wide operating temperature range for various environments
• Low quiescent current for power efficiency

Advantages and Disadvantages

Advantages

• Precise voltage monitoring ensures system reliability
• Adjustable delay time allows flexibility in system design
• Low quiescent current minimizes power consumption

Disadvantages

• Limited to a specific voltage threshold (5.0V)
• Requires an external delay time capacitor for customization

Working Principles

The TPS3705-50DGNG4 operates by comparing the input voltage (VIN) with the threshold voltage (TH). When VIN falls below TH, the internal circuitry triggers a reset signal on the open-drain output (DO). The delay time (set by an external capacitor connected to CT) determines how long the reset signal remains active after the voltage rises above the threshold.

The TPS3705-50DGNG4 finds application in various fields, including:

1. Power supply monitoring in industrial control systems
2. Battery voltage monitoring in portable devices
3. Overvoltage protection in automotive electronics
4. System reset control in microcontroller-based systems
5. Voltage supervision in communication equipment
