The 80 mOhm Rds(on) at 25°C sets the conduction loss floor — at 4 A the I²R dissipation is roughly 1.28 W, which the 14-HTSSOP exposed-pad package must sink to the PCB copper plane. The TPS1H100AQPWPRQ1 includes adjustable current limiting, open-load detection, overtemperature shutdown, and undervoltage lockout (UVLO). These protections address the common failure modes in automotive loads: shorted solenoids, broken lamp filaments, and thermal runaway from stalled motors. The adjustable current limit lets the designer set the trip threshold below the 4 A maximum to protect the load and wiring, while the open-load detect flags a disconnected harness. The UVLO prevents the switch from operating below the minimum supply voltage, avoiding partial turn-on and excessive dissipation. ## 14-HTSSOP package and thermal management Without adequate copper area, the junction temperature will exceed the 125°C rating at full load. No direct pin-compatible replacement or second-source alternate is documented in the TI family.","metaTitle":"TPS1H100AQPWPRQ1 Automotive High-Side Switch, 80 mOhm, 4 A","metaDescription":"Texas Instruments TPS1H100AQPWPRQ1 automotive AEC-Q100 high-side switch. 80 mOhm Rds(on), 4 A output, 5-40 V load range, -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":"Status Flag","Interface":"On/Off","Input Type":"-","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"80mOhm","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Active","Voltage - Load":"5V ~ 40V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Open Load Detect, Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS1H100","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TA)","Current - Output (Max)":"4A","Supplier Device Package":"14-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/397457997acee6fe0cd278047fffc80d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS1H100AQPWPRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of TPS1H100AQPWPRQ1?","answer":"The typical on-resistance is 80 mOhm at 25°C junction temperature."},{"question":"What is the direct replacement for TPS1H100AQPWPRQ1?","answer":"No direct pin-compatible replacement or official second-source alternate is documented in the Texas Instruments TPS1H100 family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS1H100AQPWPRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS1H100AQPWPRQ1 when reusing this data.
