Its AEC-Q100 and Functional Safety (FuSa) qualification means it is designed for safety-critical ECU applications where a single-point failure on the supply rail must not cause a system-level hazard. The five outputs supply the core, I/O, analog, and sensor rails for an automotive MCU or SoC. ## Package and thermal — the exposed pad is non-negotiable The 32-TSSOP with exposed pad (0.240-inch body width, 6.10 mm) is the thermal and electrical ground reference. Mounting is surface-mount only. The pitch is 0.65 mm — standard for this class of PMIC, but the exposed pad requires a solder-paste stencil aperture that covers at least 50% of the pad area for void-free reflow. ## What the five-output count means for the BOM Five outputs from a single IC replaces five discrete LDOs or a multi-phase switcher plus LDOs, saving board area and reducing the component count in the power-tree. The trade-off is single-source risk — if this PMIC fails in the field, all five rails drop. For safety-rated systems, the FuSa qualification includes diagnostic coverage for output undervoltage and overvoltage, which is the reason to use this part over a discrete solution. The 4.5V–36V input range means it can sit directly on the automotive battery line without a pre-boost or pre-buck.","metaTitle":"TPS65381AQDAPTQ1 PMIC, AEC-Q100, 5 Outputs, 4.5V–36V Input","metaDescription":"Texas Instruments TPS65381AQDAPTQ1 automotive PMIC with 5 regulated outputs, AEC-Q100 and Functional Safety (FuSa) qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100, Functional Safety (FuSa)","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive, Industrial Safety","Mounting Type":"Surface Mount","Package / Case":"32-TSSOP (0.240\\\", 6.10mm Width) Exposed Pad","Product Status":"Active","Voltage - Input":"4.5V ~ 36V","lifecycle_stage":"eol_hot","Voltage - Output":"Multiple","Number of Outputs":"5","Base Product Number":"TPS65381","Operating Temperature":"-40°C~125°C","Supplier Device Package":"32-HTSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/050c73055b99999d407b17d68bfc5647.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65381AQDAPTQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65381AQDAPTQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65381AQDAPTQ1 when reusing this data.
