The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, which saves a component and simplifies the BOM for high-density boards. ## 140 ms reset timeout — what it buys you That is the window the datasheet guarantees — the actual timeout is typically longer, but nominal is not absolute max, so budget the minimum when sizing the power-good sequence. The 140 ms minimum reset timeout provides margin for a typical power-up ramp.","metaTitle":"TI TPS3705-30DR Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3705-30DR simple reset/power-on reset IC.

It drives the reset signal low when the monitored voltage falls below the 2.63V threshold, and returns high when the supply recovers and the 140 ms timeout expires. No external pull-up resistor is needed."},{"question":"Can the TPS3705-30DR replace the TPS3705-30?","answer":"The TPS3705-30DR and TPS3705-30 share the same base product number TPS3705 and the same 2.63V threshold. The difference is the package suffix — the 'DR' variant is the 8-SOIC in Tape & Reel, while the '30' suffix without 'DR' may indicate a different package or tube delivery. Pin compatibility depends on the specific package; confirm the footprint matches your board before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3705-30DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3705-30DR when reusing this data.
