The 650 µA supply current is the controller's own draw — the pass FET's gate drive comes from the supply, so the total load current is set by the external N-channel MOSFET. With programmable slew rate, fault timeout, and circuit breaker thresholds, this controller ramps the output voltage to prevent inrush current glitches on insertion. The UVLO feature holds the FET off until the input rail is stable, avoiding partial turn-on during a brownout. ## Package and board-fit for the reeled variant Housed in an 8-lead SOIC (0.154\" body width, 3.90 mm), the LTC1422IS8#TRPBF uses the standard 8-SO footprint. The Tape & Reel (TR) packaging suits automated pick-and-place; the Cut Tape (CT) option is also available for prototyping. ## External FET architecture — what that means for the BOM Because the LTC1422 does not integrate the power switch (Internal Switch(s): No), the pass FET is a separate BOM line. This gives flexibility to choose an N-channel MOSFET rated for the actual load current and package thermal impedance, but it also adds a sourcing point. The controller itself handles the gate drive and fault monitoring.","metaTitle":"LTC1422IS8#TRPBF Hot Swap Controller, 2.7V-12V, 8-SOIC","metaDescription":"LTC1422IS8#TRPBF active Hot Swap Controller from Analog Devices. 2.7V-12V supply, 650 µA supply current, industrial temp range, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto Retry, UVLO","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"650 µA","Voltage - Supply":"2.7V ~ 12V","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Programmable Features":"Circuit Breaker, Fault Timeout, Slew Rate","Supplier Device Package":"8-SO"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.97000","currency":"USD"},{"qty":10,"price":"$9.00200","currency":"USD"},{"qty":25,"price":"$8.58320","currency":"USD"},{"qty":100,"price":"$7.45290","currency":"USD"},{"qty":250,"price":"$7.11792","currency":"USD"},{"qty":500,"price":"$6.48984","currency":"USD"},{"qty":1000,"price":"$5.92500","currency":"USD"},{"qty":2500,"price":"$5.92500","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between LTC1422IS8#TRPBF and LTC1422IS8#PBF?","answer":"The TR suffix is the reeled variant for high-volume assembly."},{"question":"What compliance documentation does Analog Devices provide for LTC1422IS8#TRPBF?","answer":"The part is ROHS3 compliant per the lifecycle record."},{"question":"How can I order LTC1422IS8#TRPBF and check availability?","answer":"The LTC1422IS8#TRPBF is sourced to order through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC1422IS8~4TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC1422IS8~4TRPBF when reusing this data.
