The 60 ms minimum reset timeout gives most MCUs and SoCs enough time to complete an orderly shutdown or hold in reset during a glitch. The active-low, push-pull output drives the processor's reset pin directly without an external pull-up. ## Package and footprint — 8-VSSOP layout notes The 0.50 mm pin pitch is manageable on a two-layer board if the bypass cap and the battery-backup capacitor sit close to the supply and backup pins. Keep the trace from the reset output to the processor under 50 mm to avoid noise coupling that could stretch the reset pulse.","metaTitle":"Texas Instruments TPS3619-33DGKR Battery Backup Circuit","metaDescription":"Battery backup supervisor IC with active-low reset, 60ms min timeout, 2.93V threshold.

It drives low when the monitored voltage falls below the 2.93 V threshold and stays low for at least 60 ms after the voltage returns above the threshold."},{"question":"Can TPS3619-33DGKR operate at 3.3 V supply voltage?","answer":"Yes, the 2.93 V threshold is designed for a nominal 3.3 V supply rail. The part monitors that rail and asserts reset before the voltage drops low enough to cause logic errors in the downstream processor."},{"question":"What is the difference between TPS3619-33DGKR and TPS3619-33DGK?","answer":"The suffix 'R' in TPS3619-33DGKR indicates Tape & Reel packaging; the TPS3619-33DGK is typically supplied in tubes or cut tape. The die, the electrical specs, and the 8-VSSOP package are identical — the only difference is the shipping medium."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3619-33DGKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3619-33DGKR when reusing this data.
