That is typical for N+1 controllers in this class: the external FET lets the designer scale the ORing path for the actual load current, from a few amps in a line card to tens of amps in a power shelf. The controller handles the gate drive and fault detection; the FET handles the current. If you need a self-contained ORing solution with the FET inside, this is not that part. ## 0°C to 70°C — indoor equipment only The operating temperature range is 0°C to 70°C, which limits this variant to controlled indoor environments — central offices, data centres, equipment rooms. For a telecom cabinet on a rooftop or an outdoor base station, the industrial-temperature sibling LTC4352IMS#PBF (-40°C to 85°C) is the correct choice. The commercial-grade CDD part is fine for a rack-mount power shelf in a climate-controlled facility.","metaTitle":"LTC4352CDD#PBF N+1 ORing Controller, 2.9V-18V, 12-DFN","metaDescription":"LTC4352CDD#PBF N+1 ORing Controller from Analog Devices. 250 ns on-delay, 200 ns off-delay, 2.9V-18V supply, 12-DFN package.

The CDD#PBF comes in a 12-DFN (3x3 mm) package in Tube; the CMS#PBF is in a 12-MSOP package. The DFN offers a smaller footprint with an exposed pad for better thermal dissipation; the MSOP is a larger, easier-to-handle package for prototyping or lower-density boards."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4352CDDPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4352CDDPBF when reusing this data.
