It lives in a SOT-23-6 package, which is small enough to tuck next to the power entry on a multi-layer board without eating routing channels. The active-low, open-drain output means you can wire-OR it with other fault signals into a shared reset line — handy when you have a supervisor per voltage domain and want a single interrupt to the MCU. ## Rated for the hot end of the board It will sit on a motor-drive board near the IGBTs or under the hood of a vehicle without drifting its thresholds from self-heating. The wide range also covers cold-crank events where the ambient drops well below freezing — the supervisor stays awake and asserts reset before the downstream logic browns out. Because the thresholds are adjustable via external resistors, the accuracy of the reset trip point depends on the resistor tolerance you choose, not on a fixed internal divider. If your assembler prefers tubes for low-volume hand-loading, that variant is the one to order.","metaTitle":"TPS3780BDBVR Multi-Voltage Supervisor, -40°C to 125°C","metaDescription":"Texas Instruments TPS3780BDBVR multi-voltage supervisor monitors two adjustable thresholds.

By setting the resistor divider ratios appropriately, the comparator window can be configured to assert reset when the monitored rail exceeds an upper limit or drops below a lower limit. The active-low output goes low on either fault."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3780BDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3780BDBVR when reusing this data.
