Single-rail supervisor with adjustable threshold and timeout
The TPS3898ADRYT is a simple reset/power-on reset supervisor from Texas Instruments, monitoring a single voltage rail and asserting an active-low, open-drain output when the supply drops below the adjustable threshold. The reset timeout period is adjustable via an external capacitor, letting the designer match the delay to the start-up timing of the downstream load — useful when sequencing a processor or FPGA core rail that needs a stable supply before release.
Package and footprint — 6-SON (1.45 mm x 1 mm)
Supply options include Tape & Reel or Cut Tape; the base product number TPS3898 covers the family variants with different preset thresholds and timeout ranges.
