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 Rated for a junction temperature range of -40°C to 125°C, this supervisor handles outdoor telecom cabinets, factory-floor motor drives, and automotive engine-bay environments. 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. ROHS3 compliant, so it passes the material declaration for EU and most global markets without an exemption expiry to watch.","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.
