That 80V ceiling covers 48V telecom buses with margin for transients, 24V industrial rails, and 12V backplane supplies without needing a pre-regulator. It does not integrate the pass FET — the external N-channel MOSFET is sized to the load current and thermal budget, which keeps the controller small in a 10-MSOP package but adds a BOM component the designer must select for Rds(on) and gate charge. ## Latched fault vs auto-retry — the -1 / -2 fork The -1 suffix means the controller latches off after a fault (overcurrent or overvoltage) and stays off until the input is cycled or the UVLO pin is toggled. The sibling LM5069MMX-2/NOPB auto-retries after a fault timeout. Pick the -1 when a fault must be investigated before restart — telecom line cards, base stations, safety-critical industrial nodes. Pick the -2 when the load can tolerate automatic recovery, like a fan tray or a redundant PSU. ## Programmable protection setpoints Four programmable features are available: current limit (set by an external sense resistor), fault timeout (capacitor on the TIMER pin), overvoltage protection (OVP resistor divider), and undervoltage lockout (UVLO resistor divider). The 1.3 mA supply current is the controller's own draw — the pass FET gate drive adds a transient load during startup. ## Package and rework note 10-MSOP with 0.118-inch (3.00 mm) body width — the 0.50 mm lead pitch is reworkable with a fine-tip iron and flux, but the small thermal pad under the package (if present on the layout) needs a preheat to avoid tombstoning.","metaTitle":"LM5069MMX-1/NOPB Hot Swap Controller, 9V-80V, Latched Fault","metaDescription":"Texas Instruments LM5069MMX-1/NOPB hot swap controller. 9V to 80V supply range, latched fault, programmable UVLO/OVP/current limit. -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Hot Swap Controller","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Latched Fault","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.3 mA","Voltage - Supply":"9V ~ 80V","Internal Switch(s)":"No","Number of Channels":"1","Base Product Number":"LM5069","Operating Temperature":"-40°C~125°C","Programmable Features":"Current Limit, Fault Timeout, OVP, UVLO","Current - Output (Max)":"-","Supplier Device Package":"10-VSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5f2ab6b5253e90daf2efcf3f6ce64753.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM5069MMX-1%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between LM5069MMX-1/NOPB and LM5069MMX-2/NOPB?","answer":"The -1 variant latches off after a fault and requires a power cycle or UVLO toggle to restart. The -2 variant auto-retries after the fault timeout. Both share the same pinout, package, and 9V-80V supply range. Choose the -1 for applications where a fault must be manually cleared; choose the -2 for automatic recovery."},{"question":"Can LM5069MMX-1/NOPB handle 48V input?","answer":"Yes. The supply range is 9V to 80V, so a nominal 48V telecom bus with transients up to 80V is within the controller's rating. The external pass FET must be selected for the 48V rail with appropriate Vds margin."},{"question":"How does the LM5069MMX-1/NOPB latch fault protection work?","answer":"When an overcurrent or overvoltage condition exceeds the programmed threshold and the fault timeout expires, the controller turns off the external pass FET and latches off. Recovery requires cycling the input supply below the UVLO threshold or toggling the UVLO pin. This prevents automatic restart into a persistent fault."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM5069MMX-1-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM5069MMX-1-NOPB when reusing this data.
