The 4.65V threshold sits at roughly 93% of a nominal 5V rail, giving early warning before the rail drops into the undefined logic region. The 16-TSSOP package with 0.65mm pitch requires a standard surface-mount assembly process and a 4-layer board if the designer wants a solid ground plane under the package.","metaTitle":"MAX791CUE+ Analog Devices Supervisor, 4.65V Threshold","metaDescription":"MAX791CUE+ Simple Reset/Power-On Reset IC, Active Low, Open Drain, 140ms timeout, 4.65V threshold, 16-TSSOP.

It prevents a microcontroller, FPGA, or other logic from starting up before the supply is stable, and it asserts reset again if the rail dips below the threshold during operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX791CUE~3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX791CUE~3 when reusing this data.
