The reset output is Active Low and Open Drain, meaning it pulls low when the monitored voltage falls below the threshold and releases to a high-impedance state when the supply recovers. This allows the output to be pulled up to a different voltage level than the monitored rail, simplifying interface with 1.8V, 2.5V, or 3.3V logic. ## Adjustable threshold and reset timeout Both the voltage threshold and the reset timeout period are adjustable/selectable via external resistors, giving the designer control over the trip point and the duration of the reset pulse. This flexibility is useful when the monitored rail has a tight tolerance or when the downstream device requires a specific reset hold time. The device monitors a single voltage and is available in a compact 6-UFDFN package (6-SON, 1.45x1 mm), suitable for space-constrained PCB layouts in portable, industrial, and automotive electronics. ## Temperature range and production status The wide junction temperature range ensures reliable reset behavior in motor drives, engine control units, and outdoor telecom equipment.","metaTitle":"TPS3898PDRYR Simple Reset/Power-On Reset IC, Active Low","metaDescription":"Texas Instruments TPS3898PDRYR Simple Reset/Power-On Reset IC with Active Low Open Drain output.
