FAQs

What is TPS3825-33DBVT?

The TPS3825-33DBVT is a voltage supervisor IC (Integrated Circuit) designed by Texas Instruments. It is commonly used to monitor the voltage level in electronic systems and provide a reset signal when the voltage falls below a preset threshold, ensuring proper system operation.

How Does TPS3825-33DBVT Work?

The TPS3825-33DBVT works by comparing the monitored voltage to a reference voltage. When the monitored voltage drops below the threshold voltage, the IC triggers a reset signal to the system, prompting it to restart or enter a safe state until the voltage returns to a normal level.

How Many Pins does TPS3825-33DBVT have and What are the Functions of the Pinout Configuration?

The TPS3825-33DBVT is housed in a 5-lead SOT-23 (Small Outline Transistor) package. The pinout configuration includes:

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

What are the Pros and Cons of TPS3825-33DBVT?

Pros:

  • Overvoltage Protection: Monitors voltage levels to prevent damage from overvoltage conditions.
  • Reset Functionality: Provides a reset signal to ensure proper system operation during voltage dips.
  • Low Power Consumption: Operates with low power consumption, suitable for power-sensitive applications.
  • Compact Package: The SOT-23 package is space-efficient, ideal for compact designs.

Cons:

  • Single Voltage Threshold: May not offer flexibility in setting multiple voltage thresholds.
  • External Components: Some applications may require additional external components for customization.

Are There Any Equivalents/Alternatives to TPS3825-33DBVT for Recommendation?

  • Alternatives to the TPS3825-33DBVT include the MAX811 from Maxim Integrated and the MCP809 from Microchip Technology.
