It operates from 4V to 80V, covering 12V automotive, 24V truck, and 48V telecom rails without an external supply regulator. Automotive AEC-Q100 qualification means this part has passed the full suite of stress tests for under-hood and chassis-domain electronics — 1000-hour HTRB, temperature cycling, and ESD robustness — so it fits production BOMs for ADAS, infotainment, and body-control modules without a separate qualification run. ## Asymmetric timing — 200 µs on, 300 ns off The turn-on delay is 200 µs, which allows the input supply to stabilise and prevents inrush current from charging a pre-biased output capacitor. The turn-off delay is 300 ns — fast enough to catch a reverse-current event before the MOSFET body diode conducts and the output voltage droops. This asymmetry is deliberate: slow start for controlled power-up, fast stop for fault containment. Supply current is 150 µA, low enough to keep the controller biased continuously in a redundant supply where one rail is always on standby. The 1:1 input-to-output ratio means each controller manages one MOSFET for one power path — no scaling needed for a single ORing stage. ## Package and footprint — 6-DFN with exposed pad Housed in a 6-WFDFN with exposed pad, the supplier device package is 6-DFN (2x3 mm).","metaTitle":"LTC4359IDCB#WTRMPBF N+1 ORing Controller, AEC-Q100, 4V-80V","metaDescription":"Analog Devices LTC4359IDCB#WTRMPBF N+1 ORing controller, automotive AEC-Q100 grade, 4V to 80V supply, 150 µA quiescent, 6-DFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Type":"N+1 ORing Controller","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Applications":"Redundant Power Supplies, Telecom Infrastructure","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"6-WFDFN Exposed Pad","Delay Time - ON":"200 µs","lifecycle_stage":"eol_hot","Current - Supply":"150 µA","Delay Time - OFF":"300 ns","Voltage - Supply":"4V ~ 80V","Internal Switch(s)":"Yes","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 85°C (TA)","Current - Output (Max)":"220µA","Supplier Device Package":"6-DFN (2x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.02","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.02000","currency":"USD"},{"qty":10,"price":"$6.34100","currency":"USD"},{"qty":25,"price":"$6.04600","currency":"USD"},{"qty":100,"price":"$5.24960","currency":"USD"},{"qty":250,"price":"$5.01364","currency":"USD"},{"qty":500,"price":"$4.57126","currency":"USD"},{"qty":1000,"price":"$3.98142","currency":"USD"},{"qty":2500,"price":"$3.83396","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ltc4359.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LTC4359IDCB#WTRMPBF AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 qualification, making it suitable for automotive-grade designs without additional stress-test qualification by the buyer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4359IDCBWTRMPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4359IDCBWTRMPBF when reusing this data.
