FAQs

What is TPS3828-33DBVT?

The TPS3828-33DBVT is a supervisory circuit with manual reset input designed by Texas Instruments. It is commonly used to monitor system voltage levels and provide a reset signal to the microcontroller or other digital logic when necessary. The device is particularly suitable for applications requiring accurate voltage monitoring and robust reset functionality.

How Does TPS3828-33DBVT Work?

The TPS3828-33DBVT operates by continuously monitoring the system voltage and comparing it to a preset threshold. When the voltage falls below the threshold, the device asserts a reset signal to the connected microcontroller, initiating a reset sequence. The manual reset input allows external control for added flexibility in system reset management.

How Many Pins does TPS3828-33DBVT have and What are the Functions of the Pinout Configuration?

The TPS3828-33DBVT is housed in a 5-pin SOT-23 (Small Outline Transistor) package. The pinout configuration includes:

  • RESET: Reset output pin.
  • MR: Manual reset input pin.
  • GND: Ground pin.
  • VDD: Power supply pin.
  • SENSE: Voltage sense input pin.

What are the Pros and Cons of TPS3828-33DBVT?

Pros:

  • Accurate Voltage Monitoring: Provides precise voltage threshold monitoring for reliable system reset management.
  • Manual Reset Input: Offers external control for manual reset initiation, enhancing system flexibility.
  • Robust Performance: Ensures reliable operation in harsh industrial environments.
  • Compact Package: The SOT-23 package is space-efficient and suitable for compact designs.

Cons:

  • External Components: May require additional external components for specific application requirements.

Are There Any Equivalents/Alternatives to TPS3828-33DBVT for Recommendation?

  • The MAX823 from Maxim Integrated is a similar supervisory circuit providing voltage monitoring and reset functionality.
  • An alternative to the TPS3828-33DBVT is the ADM811 from Analog Devices, offering comparable features for system monitoring and reset control.
