Its supply range of -9V to -100V targets -48V telecom and -72V base-station power distribution, where a single controller manages the inrush current and fault protection on a -48V rail. The part does not include an internal switch — it drives an external N-channel MOSFET pass transistor, so the current rating is set by the external FET and heatsink, not the controller itself. ## Programmable protection — what each feature controls The MAX5900AAEUT-T gives the designer control over Auto Retry, Circuit Breaker, Current Limit, Fault Timeout, Latched Fault, Slew Rate, and UVLO. Slew rate programming sets the gate turn-on ramp to limit capacitive inrush; the circuit breaker threshold and current limit define the overcurrent trip point. Fault timeout and latched fault select whether the part retries automatically or stays off after a fault. UVLO sets the undervoltage lockout threshold, which is critical for sequencing on a -48V rail that may sag during battery backup. ## Active lifecycle — no last-time-buy pressure There is no EOL notice or last-time-buy window to manage. The RoHS compliance is listed as non-compliant, so verify your assembly line's exemption allowance if you require lead-free processing. ## SOT-23-6 package — footprint and thermal note The MAX5900AAEUT-T comes in a 6-pin SOT-23 surface-mount package (Supplier Device Package SOT-23-6). The controller itself dissipates very little power — the 500 µA supply current keeps self-heating negligible — so the SOT-23 is adequate for the controller. The external MOSFET carries the load current and needs its own thermal management. The operating temperature range is -40°C to 85°C ambient, which covers indoor telecom racks and outdoor cabinets with passive cooling.","metaTitle":"MAX5900AAEUT-T Hot Swap Controller, -9V to -100V, SOT-23-6","metaDescription":"MAX5900AAEUT-T Simple Swapper™ hot swap controller for -9V to -100V rails.

The supply range of -9V to -100V covers the standard -48V telecom rail, including the typical tolerance band of -36V to -72V. The UVLO programmable feature lets you set the undervoltage threshold to match the system's brownout limits."},{"question":"What is the difference between MAX5900AAEUT and MAX5900AAEUT-T?","answer":"The suffix -T typically denotes tape-and-reel packaging in Maxim's numbering, but the listing shows the shipping medium as Bulk for this variant. The die and electrical specifications are identical between the two order codes.
