The exposed pad under the package aids thermal transfer; a solid via-in-pad layout under the pad helps keep the junction temperature down during continuous operation.","metaTitle":"TPS3831G33DQNT Texas Instruments Supervisor IC","metaDescription":"TPS3831G33DQNT Simple Reset/Power-On Reset IC from TI.

The 3.08V threshold is designed to monitor a 3.3V supply rail. When the rail falls below 3.08V, the active-low RESET output asserts, preventing the system from operating on an undervoltage supply."},{"question":"Does TPS3831G33DQNT require an external pull-up resistor?","answer":"No. The output is push-pull (totem pole), so it drives high and low without a pull-up. That saves one resistor per supervisor channel on the BOM."},{"question":"What is the difference between TPS3831G33DQNT and TPS3831G33DRVT?","answer":"The two share the same die and threshold voltage. The suffix difference is package and reel format: DQNT is the 4-X2SON (1x1 mm) in Tape & Reel; DRVT is the same package but in a different reel quantity or tape orientation. Confirm the reel quantity on the distributor listing for your volume."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3831G33DQNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3831G33DQNT when reusing this data.
