It sits between the supply rail and the load, driving an external N-channel MOSFET — there is no internal switch, so the pass FET is your choice based on the load current you need to handle. The controller itself draws 1 mA from the rail, so its own overhead is negligible in the power budget. ## Programmable fault handling — the so-what The programmable feature set includes UVLO, OVP, current limit, circuit breaker, fault timeout, and a choice between auto-retry and latched fault on overcurrent. This means you can set the undervoltage lockout threshold so the MOSFET stays off until the supply is stable, and the overvoltage protection clamps the gate if the rail spikes — both are set with external resistor dividers, not a digital interface. The circuit breaker and current limit work together: the current limit regulates the gate during startup to control inrush, and if the current stays above the limit for longer than the fault timeout, the breaker trips and the controller either retries automatically or latches off, depending on the pin strapping. This is the difference between a board that resets itself after a transient fault and one that stays dead until someone cycles power — choose the behavior that matches your system's fault recovery strategy.","metaTitle":"LTC4212CMS#PBF Hot Swap Controller, 2.5-16.5V, 10-MSOP","metaDescription":"LTC4212CMS#PBF Analog Devices hot swap controller, 2.5V to 16.5V supply, 1 mA supply current, 10-MSOP package.
