The 2.7V to 18V supply range covers the common intermediate bus voltages (3.3V, 5V, 12V) and lets you reuse the same BOM position across multiple rail voltages in a mixed-voltage chassis. ## Programmable protection set — what each feature guards against Six programmable functions are on board: circuit breaker threshold, current limit, fault timeout, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO). The circuit breaker and current limit together prevent a downstream short from pulling the bus down; the fault timeout distinguishes a transient surge from a hard fault. Auto retry and thermal limit are built in as fixed features — after a fault timeout the controller re-attempts startup, and if the die temperature exceeds the limit it latches off until the part cools, protecting against sustained overloads in a confined chassis. The 400 µA supply current is the controller's own draw — negligible against the 9A load path, so it does not eat into the thermal budget of the downstream regulator.","metaTitle":"MAX15091AETI+ Hot Swap Controller, 9A, 2.7-18V, 28-TQFN","metaDescription":"MAX15091AETI+ Analog Devices hot swap controller, 9A max output, 2.7-18V supply, 28-TQFN exposed pad.
