It provides both active-high and active-low push-pull outputs, covering the two common reset polarities without needing an external inverter. The 120ms minimum reset timeout gives the processor time to stabilise after power-up.
Housed in a SOT-23-5 (SC-74A) surface-mount package, the TPS3824-30DBVRG4 is small enough for tight layouts and easy to hand-solder with a fine-tip iron — no hot-air station needed for a field swap.
The TPS3824-30DBVRG4 provides both active-high and active-low reset outputs in a push-pull, totem-pole configuration. This dual-polarity output lets it drive processors that require either reset polarity without an external inverter.
The reset timeout is 120ms minimum. This delay holds the processor in reset long enough for the supply and oscillator to stabilise after power-up.
Yes, the 2.63V threshold is specifically chosen for 3.3V supply monitoring. It asserts reset before the supply drops below the minimum operating voltage of most 3.3V logic and MCUs.
