Functional Features
- Voltage Monitoring: The TPS3820-33DBVRG4 continuously monitors the supply voltage and generates a reset signal when it falls below the threshold voltage.
- Power-On Reset: Upon power-up, this device ensures that the system remains in a known state by delaying the reset output for a specified period.
- Watchdog Timer: The integrated watchdog timer prevents system lock-ups by generating a reset signal if the system fails to toggle a specific input within the timeout period.
Advantages and Disadvantages
Advantages
- Wide operating voltage range allows compatibility with various electronic systems.
- Low quiescent current minimizes power consumption.
- Small package size enables usage in space-constrained applications.
- Accurate voltage monitoring ensures reliable system operation.
Disadvantages
- Limited reset timeout and watchdog timer periods may not be suitable for certain applications requiring longer intervals.
Working Principles
The TPS3820-33DBVRG4 operates by comparing the supply voltage with the threshold voltage. If the supply voltage drops below the threshold, the reset output is activated. Additionally, the power-on reset delay ensures that the system remains stable during power-up. The watchdog timer monitors a specific input, and if it does not toggle within the timeout period, a reset signal is generated.
