It lets you insert a line card into a live backplane without glitching the shared -48V bus or damaging the card's input capacitors. Because it has no internal switch, you pair it with an external N-channel MOSFET that handles the inrush current. The controller ramps the gate voltage to limit the surge, then holds the FET fully on once the output is stable. ## Programmable protection and fault response Four programmable features — current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO) — let you set the safe operating window for the card. The latched fault behaviour means the controller shuts off and stays off after a fault; it does not auto-retry, so a sustained short on the card does not cause repeated power cycling. The controller itself draws 900 µA from the -48V rail, which is negligible compared to the load current the external FET switches. Housed in a 10-lead MSOP with 0.50 mm pitch, the LTC4252CCMS-1#PBF fits a compact footprint on the line-card edge near the -48V input connector. The 10-TFSOP and 10-MSOP share the same 3.00 mm body width, so the same PCB layout accepts either package variant.","metaTitle":"LTC4252CCMS-1#PBF Hot Swap Controller, -48V, 10-MSOP","metaDescription":"Analog Devices LTC4252CCMS-1#PBF hot swap controller for -48V supplies, 900 µA supply current, latched fault, 10-MSOP.
