Operating from a 1.5V to 12V supply rail and drawing 1.6 mA quiescent current, it handles low-voltage digital and mixed-signal rails without an external charge pump. ## Programmable protection and the latched-fault behavior Three programmable features — Fault Timeout, Overvoltage Protection (OVP), and Undervoltage Lockout (UVLO) — let you set the turn-on threshold and the fault-clearing interval. The latched-fault output means the controller shuts down and stays off after a fault until the input is cycled or the part is reset externally, which prevents automatic retry into a persistent short. Because the part has no internal switch, an external N-channel MOSFET handles the pass element — the controller drives the gate, so the current limit and SOA depend on the external FET you choose. This gives flexibility for higher-current rails beyond what an integrated switch could deliver in the SSOP footprint. ## Temperature range and board integration The 16-SSOP package has a 0.025\" lead pitch — standard 4-layer board fan-out works; the exposed pad on the SSOP variant is not present here, so thermal relief comes through the copper pour on the PCB. Analog Devices lists the LTC4350CGN#PBF as Active and ROHS3 compliant.","metaTitle":"LTC4350CGN#PBF Hot Swap Controller, OR Controller, 1.5-12V","metaDescription":"Analog Devices LTC4350CGN#PBF Hot Swap Controller, OR Controller.
