No exposed thermal pad to worry about, so a standard reflow profile for small-outline packages works fine. ## Temperature grade — full industrial range The 125°C ceiling is a step above many voltage detectors that stop at 105°C, giving extra margin in hot environments.","metaTitle":"ROHM BU4316G-TR Simple Reset IC, Active-Low, 1.6V Threshold","metaDescription":"ROHM BU4316G-TR simple reset/power-on reset IC.

The push-pull output drives 3.3V logic directly."},{"question":"What is the reset timeout for BU4316G-TR and how is it set?","answer":"The reset timeout is adjustable or selectable, typically set with an external capacitor connected to the delay pin. The exact timeout value depends on the capacitor chosen — the datasheet provides the formula or table for selecting the capacitor value for your desired delay."},{"question":"When sourcing BU4316G-TR, what's the closest functional second-source?","answer":"The BU4921G-TR is a close peer in the same ROHM family, but its reset polarity is active-high instead of active-low. If your design needs an active-low reset, the BU4316G-TR is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/BU4316G-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/BU4316G-TR when reusing this data.
