The 1.84V threshold is set to monitor a 1.8V nominal rail — the reset asserts when the supply falls to 1.84V, which is appropriate for 1.8V logic. The open-drain output can be pulled up to any voltage within the absolute maximum ratings of the device, so it interfaces directly with 1.8V or 3.3V logic."},{"question":"What is the difference between TPS3103H20DBVR and TPS3103H20DBVT?","answer":"The die, threshold, and electrical specifications are identical. For reel quantities, either works; for small prototype volumes, the DBVR cut-tape option may be more convenient."},{"question":"Does TPS3103H20DBVR have a manual reset input?","answer":"No. This is a simple reset IC with no manual reset (MR) input. It monitors a single voltage rail and asserts reset based solely on the supply voltage crossing the 1.84V threshold. For designs requiring a push-button or host-driven reset, look at the TPS3103 family variants with an MR pin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3103H20DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3103H20DBVR when reusing this data.
