Product details

2.93V threshold — matching the 3.3V rail

Its threshold voltage is 2.93V, which means it asserts reset when the monitored voltage drops below that level and holds reset for a minimum of 120ms after the supply recovers. The output is active high, push-pull — it drives high when reset is asserted, so it mates directly with the reset input of a processor or FPGA that expects a high-true signal.

Housed in a SOT-23-5 (SC-74A) surface-mount package, this part is a straightforward drop-in for board-level voltage monitoring. Not rated for automotive under-hood use, but fine for cabin or chassis applications that stay within the 85°C ceiling.

Frequently asked questions

Does TPS3825-33DBVRG4 have push-pull output?

Yes, the output is push-pull (totem pole) and active high. It drives high when reset is asserted, so it works with processors that expect a high-true reset signal.

What is the reset timeout of TPS3825-33DBVRG4?

The reset timeout is 120ms minimum. After the supply recovers above the threshold, the output stays asserted for at least 120ms before releasing.
