Its adjustable threshold and reset timeout let you set the trip point and hold-off period with external resistor dividers and capacitors — useful when your rail is non-standard or you need a specific power-up delay that a fixed-threshold part does not offer. Both the voltage threshold and the reset timeout period are adjustable or selectable via external components. ## Active-high, open-drain — the pull-up decision The reset output is active high with an open-drain stage. You supply your own pull-up resistor to the logic rail of the downstream device. ## Temperature range and package — where it survives The 6-UFDFN (6-SON, 1.45 mm × 1.0 mm) package is small enough for space-constrained PCBs but has an exposed thermal pad that needs a via-stitched copper land on the PCB to pull heat into the inner layers.","metaTitle":"TPS3897ADRYR Simple Reset/Power-On Reset, Active High","metaDescription":"Texas Instruments TPS3897ADRYR simple reset/power-on reset IC.
