That 0.45V below the nominal rail gives headroom for transient droop without false resets, but still catches a brownout before the processor's logic supply collapses. The output is push-pull, totem pole, and the device supports both active-high and active-low reset assertion, so a single part can drive a /RESET pin (pull low on fault) or a RESET pin (pull high on fault) without an external inverter. ## SOT-23-5 package and supply range The 5-pin footprint is common across the TPS3824 family, easing layout reuse. The device monitors a single voltage and requires no external timing capacitor — the 120ms timeout is fixed internally, reducing BOM count and eliminating a potential tolerance drift path. No stock-holding claim — each order is sourced per RFQ.","metaTitle":"TPS3824-50DBVT Supervisor IC – 4.55V Threshold","metaDescription":"Texas Instruments TPS3824-50DBVT Simple Reset/Power-On Reset IC. 4.55V threshold, 120ms min timeout, push-pull output, SOT-23-5.

The TPS3824-50DBVT provides a push-pull output that can be configured for active-high or active-low assertion. Pin /RESET drives low on fault; pin RESET drives high on fault — two separate outputs on the same chip."},{"question":"What is the closest functional second-source to TPS3824-50DBVT?","answer":"The TLV803EA29VDBZR is a similar simple reset supervisor from TI, but it differs in key parameters: its threshold is 2.93V (not 4.55V), its output is open-drain (not push-pull), and its timeout is 130ms minimum vs 120ms. The TLV803ED29DBZR has a 33ms timeout. Neither is a direct pin-for-pin replacement for the TPS3824-50DBVT — confirm your voltage threshold and output type before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3824-50DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3824-50DBVT when reusing this data.
