When the monitored rail drops below 2.9V, the open-drain output pulls low and stays asserted for a typical 40µs after the rail recovers, then releases. That 40µs timeout is short enough to avoid holding a processor in reset through a brief brownout, but long enough to debounce a glitch on a noisy supply. ## Open-drain output and temperature range The open-drain output (active-low) lets you pull up the reset line to any voltage the downstream logic needs — 1.8V, 3.3V, or 5V — without a level shifter. For BOM planning, this is a low-risk line — no imminent obsolescence to budget for.","metaTitle":"TPS3899DL29DSER Voltage Monitor - 2.9V Threshold","metaDescription":"Texas Instruments TPS3899DL29DSER voltage monitor with 2.9V threshold, active-low open-drain reset, 40µs timeout, -40°C to 125°C range.

The main difference is the reset timeout: the TPS3899DL29DSER has a 40µs typical timeout, while the TLV803ED29DBZR has a 33ms minimum timeout — a factor of about 800× longer. If your application needs a fast recovery after a brownout, the TPS3899DL29DSER is the better fit; if you need a longer reset pulse to let a supply stabilize, the TLV803ED29DBZR is the choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3899DL29DSER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3899DL29DSER when reusing this data.
