It asserts a reset output when the monitored supply drops below that threshold, then releases after a 15ms minimum timeout once the supply recovers. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor. The part is ROHS3 compliant, and the base product number TPS3820 covers multiple threshold variants — the -50 suffix denotes the 4.55V trip point. ## SOT-23-5 package – board footprint Supplied in a SOT-753 package, also referred to as SOT-23-5. The 5-pin footprint is common for small supervisory ICs.","metaTitle":"TPS3820-50DBVT – Texas Instruments Simple Reset/Power-On","metaDescription":"TPS3820-50DBVT from Texas Instruments – Simple Reset/Power-On Reset, Active Low, Push-Pull output, 4.55V threshold, SOT-23-5.

TPS3820-50DBVT monitors a 4.55V rail; the -33 variant monitors a 3.3V rail. All other specs — reset type, output, timeout, package, temperature range — are identical across the TPS3820 family."},{"question":"Does TPS3820-50DBVT have an open-drain output?","answer":"No. The output is push-pull, totem pole. It drives high and low actively, so no external pull-up resistor is required. If your design expects an open-drain reset output, consider the TLV803ED29DBZR, which uses an open-drain output stage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3820-50DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3820-50DBVT when reusing this data.
