The 2.63V threshold sits about 12% below a 3.0V rail, giving the supply enough droop headroom before the reset fires, but it will trip early on a 3.3V rail that normally stays above 3.0V. If your BOM calls for 3.3V monitoring, you want the TPS3824-33 variant instead. ## 120 ms reset timeout — startup margin The reset timeout is a minimum 120 ms — after the supply rises above the threshold, the output stays asserted for at least that window before releasing the processor from reset. That 120 ms floor gives a typical MCU or DSP enough time for its internal oscillator to stabilize and the boot ROM to begin execution. If your processor needs a longer delay to settle a PLL or wait for an external oscillator, you would need an external RC delay or a supervisor with a programmable timeout. ## Active high and active low — dual output flexibility This part provides both active-high and active-low reset outputs from a single push-pull stage. That means one device can drive the reset pin of a processor that expects a logic-low reset signal and simultaneously feed a status LED or enable line that needs a logic-high during reset. No external inverter needed. The push-pull output eliminates the pull-up resistor required by open-drain supervisors, saving one component per BOM line. ## SOT-23-5 footprint and temperature grade For those, look at the automotive-qualified TPS3824-Q1 family.","metaTitle":"TPS3824-30DBVT Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3824-30DBVT simple reset/power-on reset IC with 2.63V threshold, 120ms min timeout, active high/low outputs.

The 2.63V threshold is too low for a 3.3V rail — the supervisor would not detect a brownout until the supply has already dropped well below the normal operating range of most 3.3V logic. For 3.3V monitoring, use the TPS3824-33 variant."},{"question":"What is the reset timeout of TPS3824-30DBVT?","answer":"The reset timeout is a minimum of 120 ms.
