Its supply range of -9V to -100V targets -48V telecom rectifiers, -72V central-office battery plants, and other high-voltage negative-rail systems common in networking infrastructure. The controller operates from -40°C to 85°C, covering indoor telecom shelters and industrial cabinets where ambient temperature stays within that band. ## Protection features — what you can program The MAX5900AAEUT integrates programmable fault handling: auto retry or latched fault on overcurrent, an adjustable circuit-breaker threshold, current limit, fault timeout, and slew-rate control to shape the inrush profile. Undervoltage lockout (UVLO) holds the external N-channel FET off until the supply rail is within specification. Because the controller has no internal switch, the designer selects the external MOSFET sized for the load current and thermal budget — common in high-current line cards where the pass element must be matched to the dissipation. ## Supply current and thermal considerations Quiescent supply current is 500 µA, which keeps the controller's own dissipation negligible even in always-on power-distribution sections. The SOT-23-6 package (supplier device package SOT-23-6) is surface-mount and fits dense PCB layouts typical of blade servers and line cards. No heatsinking is needed for the controller itself — the external MOSFET handles the load current. ## Lifecycle and sourcing It is RoHS non-compliant per the manufacturer's declaration, so verify your assembly house's exemption policy if the build requires RoHS conformance.","metaTitle":"MAX5900AAEUT Hot Swap Controller, Simple Swapper™","metaDescription":"MAX5900AAEUT hot swap controller from Maxim's Simple Swapper™ series.

The primary difference is the fault-handling behavior: the MAX5900AAEUT offers both auto-retry and latched-fault options, while the MAX5901AAEUT provides a different fault-response scheme. Check the respective datasheets for the exact fault-timing and retry logic that matches your system's protection philosophy."},{"question":"What is MAX5900AAEUT's listed type (Hot Swap Controller) on this component line?","answer":"The MAX5900AAEUT is listed as a Hot Swap Controller in the Simple Swapper™ series. It is a single-channel controller with no internal switch, relying on an external N-channel MOSFET for pass-element duty."},{"question":"Can MAX5900AAEUT be used in -48V systems?","answer":"Yes. The supply range of -9V to -100V comfortably covers the nominal -48V telecom rail, including the -36V to -72V extremes typical of battery-backed central-office plants."},{"question":"What is a hot swap controller used for?","answer":"A hot-swap controller manages the inrush current when a circuit board is plugged into a live backplane, preventing voltage droop, connector arcing, and downstream latch-up.
