Drives an external N-channel MOSFET to manage inrush current and protect against overcurrent and short circuits. ## Package and mounting The controller's programmable UVLO and OVP let you set the undervoltage and overvoltage thresholds with an external resistor divider, matching the -48 V rail's tolerance band. The current-limit and fault-timeout pins set the inrush profile and the interval before the part declares a fault. Auto Retry means the board does not need a power-cycle or manual reset after a transient overload — the controller will keep trying to bring the load up. That is useful in remote or unattended equipment, but not in systems where a latched-off response is preferred for safety or diagnostic clarity. ## Temperature grade and where it fits The 0°C to 70°C range fits controlled indoor environments — telecom central offices, server rooms, and indoor base-station cabinets. If the board must survive outdoor cabinets, unheated shelters, or industrial floor conditions, the LTC4252-2IMS#PBF (industrial grade, -40°C to 85°C) is the same controller in the same footprint, just with the wider temperature range.","metaTitle":"LTC4252-2CMS#PBF Hot Swap Controller, -48V, 10-MSOP","metaDescription":"LTC4252-2CMS#PBF is a single-channel -48V hot swap controller with auto retry, 800 µA supply, in a 10-MSOP package.
