FAQs

What is TPS3808G09DBVRG4?

The TPS3808G09DBVRG4 is a low-power supply voltage supervisor from Texas Instruments. It is designed to monitor the voltage level of a system and provide a reset signal when the voltage falls below a specified threshold. This device is commonly used in microcontroller-based systems, battery-powered devices, and industrial control systems to ensure proper system operation during power transitions.

How Does TPS3808G09DBVRG4 Work?

The TPS3808G09DBVRG4 works by continuously monitoring the voltage at its input pin. When the voltage falls below the specified threshold, the device asserts a reset signal to the microcontroller or system, initiating a controlled reset. Once the voltage rises above the threshold, the reset signal is de-asserted, allowing the system to resume normal operation.

How Many Pins does TPS3808G09DBVRG4 have and What are the Functions of the Pinout Configuration?

The TPS3808G09DBVRG4 is housed in a 5-lead SOT-23 package. The pinout configuration includes:

  • GND: Ground connection.
  • MR: Manual reset input pin.
  • VDD: Supply voltage input pin.
  • RESET: Reset output pin.
  • VDD: Supply voltage input pin.

What are the Pros and Cons of TPS3808G09DBVRG4?

Pros:

  • Low Power Consumption: Operates with very low power, suitable for battery-powered systems.
  • Voltage Monitoring: Provides reliable voltage monitoring and reset functionality for system protection.
  • Small Package: The 5-lead SOT-23 package is compact, saving board space in designs.
  • Wide Operating Range: Supports a wide input voltage range, enhancing versatility in various applications.

Cons:

  • Manual Reset Pin: The presence of a manual reset pin may add complexity to the system design if not utilized properly.
  • Fixed Threshold: Some applications may require adjustable threshold levels, which may not be available in this device.

Are There Any Equivalents/Alternatives to TPS3808G09DBVRG4 for Recommendation?

Similar products to the TPS3808G09DBVRG4 include the MAX6746XK+T from Maxim Integrated and the ADM811 from Analog Devices.
