It operates from a 10.8V to 36V supply and draws 1.9 mA supply current. The controller does not integrate a pass FET — you add an external N-channel MOSFET sized for your load current. Programmable features include auto retry, current limit, fault timeout, latched fault, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO). This set covers the main protection axes needed for a controlled board insertion: limit the surge, clamp the voltage, and decide whether to retry or latch off after a fault. ## 16-SSOP — rework and footprint notes The LT4254CGN#PBF comes in a 16-SSOP package (0.154\" body width, 3.90 mm width). It is a surface-mount part. Rated for the commercial temperature range of 0°C to 70°C, so it is suited for indoor equipment, telecom racks, and general-purpose backplane applications where the ambient stays within that window. Not rated for industrial or automotive environments. ## Active production, no LTB risk It is also ROHS3 compliant, so it meets the current EU restriction requirements for lead-free assembly. No lead (Pb) in the plating or solder terminations.","metaTitle":"LT4254CGN#PBF Hot Swap Controller, 10.8V–36V, 16-SSOP","metaDescription":"Analog Devices LT4254CGN#PBF hot swap controller, 10.8V–36V supply, 1.9 mA supply current, programmable UVLO/OVP/current limit/slew rate, 16-SSOP, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller","Package":"Tube","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.9 mA","Voltage - Supply":"10.8V ~ 36V","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"0°C ~ 70°C","Programmable Features":"Auto Retry, Current Limit, Fault Timeout, Latched Fault, OVP, Slew Rate, UVLO","Supplier Device Package":"16-SSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.63","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.63000","currency":"USD"},{"qty":10,"price":"$5.95400","currency":"USD"},{"qty":25,"price":"$5.62880","currency":"USD"},{"qty":100,"price":"$4.87810","currency":"USD"},{"qty":250,"price":"$4.62796","currency":"USD"},{"qty":500,"price":"$4.15266","currency":"USD"},{"qty":1000,"price":"$3.54000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8f40d79555dcc7a410d1da0beb6e9d87.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the programmable features of LT4254CGN#PBF?","answer":"The LT4254CGN#PBF offers programmable auto retry, current limit, fault timeout, latched fault, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO).
