Asserts a reset signal when the supply drops below a 4.38 V threshold. Reset is active-low, push-pull. The 130 ms minimum reset timeout holds the reset long enough for system stabilization. ## Temperature grade and package — industrial and under-hood capable The SOT-23-3 package is a three-pin footprint that fits tight layouts and is compatible with standard pick-and-place assembly. Surface-mount only — no through-hole variant. ## Active lifecycle — no LTB concern for new builds TI lists the TLV809EA43DBZR as Active. That means no last-time-buy window to track and no imminent obsolescence risk for production planning.","metaTitle":"TLV809EA43DBZR Simple Reset/Power-On Reset, 4.38V Threshold","metaDescription":"TI TLV809EA43DBZR supervisor IC, active-low push-pull output, 130ms reset timeout, -40°C to 125°C, SOT-23-3.

The 130 ms reset timeout is common to both. Choose the TLV809 for 5 V rails and a simpler BOM; choose the TLV803 for 3.3 V or 2.5 V rails where an open-drain wired-OR reset bus is needed."},{"question":"Is TLV809EA43DBZR RoHS compliant?","answer":"Yes.
