The TPS3818G25DRVT is listed as active by Texas Instruments. There is no end-of-life notice or last-time-buy window, so it remains a valid choice for new designs and production builds.
The reset timeout is a minimum of 180ms. After the monitored voltage rises above the threshold, the output holds reset low for at least 180ms before releasing, giving downstream devices time to complete their power-on reset sequence.
The TPS3818G25DRVT has an active-low reset output. When the monitored voltage falls below the threshold, the output goes low and stays low through the timeout period.
It comes in a 6-WSON (2x2) package — a 6-pin WDFN with an exposed thermal pad, measuring 2 mm by 2 mm. The supplier device package is 6-WSON (2x2).
The TLV803EA29VDBZR is a similar simple reset/power-on reset supervisor from TI with an active-low, open-drain output, but it has a 130ms minimum reset timeout and a different threshold voltage (2.93V). It is not a direct pin-for-pin replacement — the TPS3818G25DRVT uses a 6-WSON package while the TLV803EA29VDBZR comes in a SOT-23. For a 2.5V rail with a 2.33V threshold and 180ms timeout, the TPS3818G25DRVT is the correct fit.
