FAQs
What is TPS3103K33DBVR?
The TPS3103K33DBVR is a voltage supervisor and reset IC (integrated circuit) manufactured by Texas Instruments. It provides monitoring and control functions for ensuring proper power supply voltage levels in various electronic systems, such as microcontrollers, DSPs, and embedded systems.
How Does TPS3103K33DBVR Work?
The TPS3103K33DBVR operates by continuously monitoring the input voltage level. It compares the input voltage against a predefined threshold and generates a reset signal when the voltage falls below the threshold. This reset signal can be used to trigger a system reset or shutdown to prevent malfunctions or data corruption in the event of a power supply issue.
How Many Pins does TPS3103K33DBVR have and What are the Functions of the Pinout Configuration?
The TPS3103K33DBVR comes in a 5-pin SOT-23 package. The pinout configuration includes:
- RESET: Reset output pin that goes low when the voltage falls below the threshold.
- VDD: Supply voltage input.
- GND: Ground connection.
- MR: Manual reset input for external reset control.
- SENSE: Voltage sense input for monitoring the power supply voltage.
What are the Pros and Cons of TPS3103K33DBVR?
Pros:
- Overvoltage Protection: Ensures stability and reliability by monitoring voltage levels.
- Reset Functionality: Provides a reset signal to prevent system malfunctions during power supply irregularities.
- Low Power Consumption: Operates with low quiescent current, suitable for power-sensitive applications.
- Small Package: The compact SOT-23 package saves board space in compact designs.
Cons:
- External Components: May require additional components for specific application requirements.
- Programming Threshold: Fixed voltage threshold may not be adjustable for custom applications.
Are There Any Equivalents/Alternatives to TPS3103K33DBVR for Recommendation?
- The TPS3808G01 from Texas Instruments offers similar voltage monitoring and reset functionality.
- Alternatives to the TPS3103K33DBVR include the MAX823 from Maxim Integrated and the ADM809 from Analog Devices.
