FAQs

What is TPS3808G01DRVT?

The TPS3808G01DRVT is a voltage supervisor and reset IC (integrated circuit) manufactured by Texas Instruments. It is designed to monitor the system voltage and provide a reset signal to the microcontroller or other digital logic when the voltage falls below a specified threshold. This helps ensure reliable operation and safe power-on and power-off sequences in electronic systems.

How Does TPS3808G01DRVT Work?

The TPS3808G01DRVT works by continuously monitoring the system voltage and comparing it to a predefined threshold. When the voltage drops below the threshold, the TPS3808G01DRVT asserts a reset signal to the connected microcontroller or logic device, prompting a controlled reset of the system. This helps prevent erratic behavior or data corruption during power fluctuations or brownout conditions.

How Many Pins does TPS3808G01DRVT have and What are the Functions of the Pinout Configuration?

The TPS3808G01DRVT is housed in a 6-pin SOT-23 (Small Outline Transistor) package. The pinout configuration includes:

  • RESET: Output pin for the reset signal.
  • MR: Manual reset input pin for external reset control.
  • GND: Ground pin.
  • VDD: Positive power supply pin.
  • SENSE: Voltage sense input for monitoring the system voltage.
  • RESET: Open-drain reset output, active-low.

What are the Pros and Cons of TPS3808G01DRVT?

Pros:

  • System Protection: Helps prevent data corruption and erratic behavior during voltage fluctuations.
  • Small Package: The SOT-23 package is compact and suitable for space-constrained designs.
  • Low Power Consumption: Operates with low quiescent current, suitable for battery-powered applications.
  • Wide Voltage Range: Supports a wide range of supply voltages for versatility in system design.
  • Manual Reset Input: Provides flexibility for external reset control if needed.

Cons:

  • External Components: May require additional external components for voltage monitoring and filtering.
  • Sensitivity to Noise: Requires attention to layout and noise immunity for reliable operation in noisy environments.

Are There Any Equivalents/Alternatives to TPS3808G01DRVT for Recommendation?

  • The MAX809 from Maxim Integrated and the ADM811 from Analog Devices are alternative voltage supervisors with similar functionality.
  • An equivalent part to the TPS3808G01DRVT is the TPS3809 family of voltage supervisors from Texas Instruments.
