A slower part risks a bus collapse in a -48V system where the holdup capacitance is sized for milliseconds, not microseconds. Quiescent supply current is 2 mA, a reasonable overhead for a redundant power controller that stays active continuously. The part does not integrate the power FETs internally (Internal Switch(s): No), so the designer selects external N-channel MOSFETs sized to the load current and the worst-case fault energy. ## Package and footprint — 16-MSOP Surface-mount assembly with standard reflow profiles applies. It is ROHS3 compliant.","metaTitle":"LTC4355HMS#TRPBF N+1 ORing Controller, -48V, 300ns","metaDescription":"Active LTC4355HMS#TRPBF N+1 ORing Controller from Analog Devices. 2:1 input ratio, 300ns turn-off, -40°C to 125°C, 16-MSOP.
