5. VIT: Voltage Input Test. Used for monitoring the supply voltage.
6. NC: No Connection.

Functional Features

• Precision Monitoring: The TPS3808G01DRVT accurately monitors the supply voltage and provides a reset signal when it falls below a specified threshold.
• Manual Reset: The manual reset input allows for a forced system reset.
• Power-On Reset Delay: The device includes a fixed delay time after power-up to ensure stable operation before releasing the reset signal.
• Low Power Consumption: With a quiescent current of only 1.6µA, the TPS3808G01DRVT minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - High precision voltage monitoring - Low power consumption - Manual reset capability - Small package size

Disadvantages: - Limited threshold voltage options

Working Principles

The TPS3808G01DRVT operates by comparing the supply voltage with a programmable threshold voltage. When the supply voltage falls below the threshold, the reset output is asserted low, indicating a system reset condition. The device includes hysteresis to prevent false triggering due to noise or voltage fluctuations.

Detailed Application Field Plans

The TPS3808G01DRVT is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some typical application fields include:

1. Microcontrollers: Ensuring proper operation and preventing data corruption during power supply fluctuations.
2. Industrial Control Systems: Providing reliable reset functionality for critical control systems.
3. Automotive Electronics: Monitoring and resetting microcontrollers and other electronic components in automotive applications.
4. Battery-Powered Devices: Protecting battery life by initiating a reset when the supply voltage drops below a certain level.
