Its headline number is the 8 mOhm typical Rds(on) — at 70 A continuous output that translates to roughly 39 W of conduction loss at 25°C junction, which climbs with temperature per the normalised curve. ## Fault protection set without external parts The adjustable current limit lets you set the trip point with a single resistor, avoiding the cost and board area of a sense resistor and comparator. The built-in fault coverage includes over-current, over-temperature, reverse-current blocking, and UVLO — the switch shuts itself off rather than letting the load cook the wiring harness. For a 12 V nominal automotive rail, the 3 V to 28 V supply range covers cold-crank down to 3 V and load-dump transients up to 28 V without external clamping. ## Active production, no LTB on the horizon For a production program that needs AEC-Q100 qualification and a 125°C operating range, this part is a stable BOM line — no forced redesign cycle from obsolescence risk.","metaTitle":"TPS1HB08BQPWPRQ1 Automotive High-Side Switch, 8 mOhm, 70 A","metaDescription":"TI TPS1HB08BQPWPRQ1 AEC-Q100 high-side switch: 8 mOhm Rds(on), 70 A max output, adjustable current limiting, -40 to 125°C.","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","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"-","Interface":"-","Input Type":"-","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"8mOhm","Mounting Type":"Surface Mount","Package / Case":"16-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - Load":"-","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Current, Over Temperature, Reverse Current, UVLO","Number of Outputs":"1","Base Product Number":"TPS1HB08","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C","Current - Output (Max)":"70A","Supplier Device Package":"16-HTSSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 28V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd0aae5498510dc8c905285b8d672b2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS1HB08BQPWPRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS1HB08BQPWPRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS1HB08BQPWPRQ1 when reusing this data.
