This part is designed for 3.3V nominal rails where a 2.64V threshold provides a clean brownout detection window before the core logic loses state. ## Active low, open-drain output — reset polarity and pull-up The reset output is active low, meaning the output goes low when the monitored voltage falls below the threshold and stays low through the timeout period after recovery. This output topology allows the reset signal to be shared with other open-drain devices on the same line without contention. ## SOT-23-5 package and industrial temperature range","metaTitle":"TPS3838L30DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3838L30DBVRG4 simple reset/power-on reset IC.
