Product details

What the 2.93 V threshold and 120 ms timeout mean for your processor supervision

The TPS3839K33DBZT: The reset remains asserted for a minimum of 120 ms after the supply recovers above the threshold, giving the processor time to stabilise before code execution starts.

Active-low push-pull output — no external pull-up needed

The reset output is active low with a push-pull, totem-pole stage. That means the output drives both high and low without requiring an external pull-up resistor, simplifying the board layout and reducing BOM count.

SOT-23-3 package and surface-mount assembly

Housed in a SOT-23-3 (TO-236-3, SC-59) package, this part is a straightforward surface-mount component for automated assembly. The three-pin footprint fits into compact designs where board space is tight.

Frequently asked questions

What is the reset timeout for TPS3839K33DBZT?

The reset timeout is a minimum of 120 ms. After the supply voltage rises above the 2.93 V threshold, the reset output stays low for at least 120 ms before releasing the processor.

Is TPS3839K33DBZT active low output?

Yes, the reset output is active low. The push-pull stage drives the output low when the monitored voltage falls below 2.93 V, and releases high after the timeout period.
