Frequently Asked Questions
What is the reset threshold voltage of the TPS3809K33DBVRG4?
The TPS3809K33DBVRG4 is factory-set to monitor a 3.3V supply rail. It asserts an active-low reset signal when the supply voltage drops below approximately 3.08V (typical), and releases the reset after the supply rises above the threshold and the 200ms timeout delay elapses.
What is the reset timeout delay and why does it matter?
The TPS3809K33DBVRG4 features a fixed 200ms reset timeout delay. After the monitored supply voltage rises above the reset threshold, the IC holds the reset line active for 200ms to ensure the power supply is fully stable before releasing the microcontroller or processor from reset, preventing erratic startup behavior.
What are typical applications for the TPS3809K33DBVRG4?
This device is commonly used in embedded systems, microcontroller boards, industrial controllers, and IoT nodes that operate from a 3.3V supply. It provides reliable power-on reset and brownout detection, replacing discrete RC reset circuits with a more accurate and temperature-stable solution.
Can I replace the TPS3809K33DBVRG4 with a pin-compatible alternative?
Yes, pin-compatible alternatives in the SOT-23-3 package include the MCP809, MAX803, and similar 3-pin voltage supervisors set to the 3.3V threshold. However, verify the exact reset threshold, timeout delay, and output logic polarity before substituting, as these parameters vary by manufacturer and part number suffix.
