With an active-low, open-drain output, it can pull a reset line low when the monitored voltage drops below threshold, and the open-drain topology allows wired-OR connection with other reset sources. ## Adjustable reset timeout — flexibility per system need The reset timeout is adjustable via an external capacitor on the CT pin, letting you set the delay from a few milliseconds to several seconds depending on the processor or FPGA power-up sequencing requirements. This adjustability means the same base part number can serve multiple BOM variants by changing one passive component, reducing qualification overhead. ## Temperature range and package — industrial and automotive ready The SOT-23-6 package keeps the footprint small (roughly 3×3 mm), which helps on dense PCBs where every square millimeter counts.","metaTitle":"TPS3808G18DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G18DBVTG4 simple reset/power-on reset IC.
